June 2016 – Summary

June was a month of two halves, the first being warm and dry with copious amounts of sunshine during which time we experienced record high temperatures for the time of year, the latter dull, wet and windy.

The month began with clear skies and 16 hours of sunshine on the 1st. The weather continued in this vein until the 17th, during which time there were 7 days when temperatures rose above 20°C, the highest being 23.3°C on the 5th, a record high for the month of June. We also recorded our highest June Heat Index (23.3°C), and highest Daily Temperature Range (12.2°C) on the same day . Our highest June Apparent Temperature (24.3°C) and Dew Point (18.0°C) was also recorded on the 6th and 7th respectively.

During this period, there were 12 dry days and only 8.4mm of rain. This minimal amount accompanied lower than average rainfall during the previous two months, prompting the local water company to issue a warning to every household regarding water usage and the need to conserve supplies. This was tantamount to a hosepipe ban and prompted discussions about a drought and the phrase “we need some rain” was to be heard for the first time in living memory.

Those who uttered the phrase were soon to have their wish granted as the wind veered to the south on the 18th bringing cloud, rain and lower temperatures until the end of the month. Despite the fall in temperatures, the month ended as our warmest June with an average temperature (1 minute) of 13.8°C.

Spring 2016 – Summary

The snow and below average temperatures in April were countered by the clear skies and higher temperatures of May, which ensured that statistically, Spring 2016 passed without too much of note.

The passage of March was uneventful apart from it being the calmest here at Askernish. Temperatures struggled in April in a keen wind and there were four consecutive days when snow fell towards the end of the month. Although the winds remained northerly in May, the dry, clear weather resulted in record amounts of sunshine and days when the temperature rose above 15°C.

May 2016 – Summary

Predominantly northerly winds are always associated with settled and clear conditions at this time of year. Such was the case this month, resulting in below average rainfall and record amounts of sunshine. Despite the same winds maintaining a keen edge, it could not prevent this May from being our warmest here at Askernish.

 

Northerly winds dominated the month of May, broken only by two brief spells (1st-5th and 16th-20th) when weak Atlantic fronts brought more humid conditions from the south. It was during these two spells that all but 1.8mm of the total months rain (39.2mm) fell with the wettest day being the 1st.

For the remainder of the month, it was clear, bright and sunny. Despite it feeling chill at times in the wind, temperatures reached 20°C on four consecutive days (8th-11th), with a high of 26.7°C on the 9th. It was on this day that the humidity fell to 33%, a record low for May and equaling our station record.

With the clear skies and long days, there was a station record high of 243.4 hours of sunshine with 15.8 hours on the 25th.

March 2016 – Summary

Yet another month when many records tumbled, a continuing trend which shows no signs of abating. Most noticeable was that this was our calmest March and there were 10 consecutive days without rain.

A prolonged calm and dry spell ensured that this was our calmest March with an average wind speed of just 9.0mph resulting in a wind run of 6668.1 miles. During this period, no rain was recorded on 10 consecutive days between 13th – 22nd and the 16th was our sunniest March day with 10.1 hours of sunshine. Also the highest March temperature (15.4°C) and the highest March daily temperature range of 11.1°C (15.4°C – 4.3°C) was recorded on the 15th plus the highest March apparent temperature of 14.1°C occurred on the 16th.

Despite the prolonged dry spell, rainfall for the month was above average helped by 17mm falling on the 25th, our wettest March day.

2 other records of note were: the lowest March humidity of 39% recorded on the 15th and the lowest March pressure recorded, that of 969.1mb during the early hours of the 26th.

February 2016 – Summary

February was yet another month when many new records were set. Not only was it our coldest and sunniest February, it also produced our windiest day and highest rain rate ever here at Askernish.

Low temperatures dominated the month with the mercury never exceeding 10°C. With a mean temperature of just 4.8°C for the month, this was our coldest February and an overnight low of 3.2°C on 14th was our lowest February temperature. Clearing skies and low overnight temperatures later in the month produced not only our highest February daily temperature range of 11.7°C (9.9 to -1.2) but also our sunniest February day on the 27th.

The wind was a feature early in the month with winds gusting to 71mph on the 1st, our highest February wind speed. The average wind speed for that day was 33.9mph resulting in a wind run of 814 miles making it our windiest ever day here at Askernish.

Heavy rain fell on the 15th and 16th during which time 4.0mm of rain fell in 1 hour, our highest February hourly rain rate on the 16th and a rain rate of 192.0mm/hour occurred early on 11th , a record for this station

January 2016 – Summary

It seems that hardly a month goes by these days without a record being broken. While the wind and rain continued to dominate our weather throughout January, no headline records were broken despite the best efforts of Gertrude, our seventh storm of the winter. There was however some very unseasonal high temperatures elsewhere in the UK and during one such period we recorded our highest ever January temperature. With so much cloud accumulation associated with these weather patterns and high temperatures, it was no surprise that this was our dullest January.

Looking back over the month, it was dull, wet and windy. It began in that fashion with slightly lower than average temperatures and rainfall, with winds gusting to 45mph in an easterly air steam until the wind backed North on the 10th. This brought calmer, clearer conditions with less cloud and wind during which time we experienced some sunshine but lower temperatures. Our only two air frosts of the month occurred on the 13th and then again on the 15th when temperatures fell to -2.2°C but oddly enough, the 15th was our sunniest ever January day with 4.0 hours of sunshine being recorded. Some cloud developed on the 16th raising the temperature slightly until Southerlies brought much warmer and humid conditions from the 22nd onwards.

Our highest ever January temperature of 11.2°C occurred on the 22nd, only to be superseded on 24th when the mercury reached 12.3°C. Several associated records were also broken for January, that of Heat Index (12.3°C) and Dew Point (11.4°C). We also recorded our highest ever January Minimum Temperature on same day when the temperature did not fall below 10.7°C.

A series of Atlantic fronts driving in from the south, dragging extremely moist air with it meant that certain parts of the UK again experienced high winds, torrential rain and flooding. For us, the heaviest rain fell early morning on the 23rd when 9.8mm fell in just 1 hour, another January record here at Askernish.

High winds and rain continued until the 28th when Gertrude arrived bringing lower temperatures, more rain, sleet and snow showers and stronger winds resulting in 2 consecutive gale days and our lowest ever January Apparent Temperature of -12.0°C on 29th.

December 2015 – Summary

While the wet and windy conditions continued to dominate our weather with storms Desmond, Eva and Frank visiting our islands, it was the temperature that was the meteological highlight of the month with it being our warmest December on record, as it was for the rest of the UK.

Wet and windy was how December started and continued through until the new year. Despite these conditions being the most memorable, the only record to be broken was our highest ever
December rain rate, that of 67.0mm/hour on the 9th. The first of the December storms to arrive on our shores late on the 4th was Desmond, which brought winds of up to 58mph and heavy rain, but nothing like that which was experienced elsewhere in the UK especially Cumbria, where there was widespread flooding and record rainfall.

Dull, wet and breezy conditions continued until the 10th when a brief spell of brighter and calmer conditions occurred and although it was still wet, it was colder with the only air frost of the month on the 12th. The 10th saw our lowest ever December humidity (58%) and the 14th was our first dry December day since 26th December 2012!

The winds increased from the 15th onwards, but on that day we experienced our highest ever December temperature with the mercury rising to 12.6°C. Our highest ever December Heat Index (12.6’C), Dew Point (12.1°C) and Apparent Temperature (12.6°C) also occurred on that day as well as our highest ever December Minimum Temperature of 10.8°C.

It remained wet and windy to such an extent that Eva passed off shore almost un-noticed overnight on the 23rd. with winds gusting to 53mph. Heavy overnight rain on the 28th signalled the imminent arrival of Frank which hit our shores on the 29th , but again it was the mainland which bore the brunt of the winds and heavy rain resulting in yet more severe flooding. A total of 35.4mm of rain fell in 48 hours with winds peaking at 65 mph, the highest recorded during the month.

Throughout the month, temperatures remained high although it felt chill in the strong winds. With an average temperature of 7.7°C, it was our warmest December here at Askernish.

Two other records of note during the month was that the maximum wind gust of 65 mph was the lowest maximum to be recorded in any December as was the maximum December atmospheric
pressure of 1018.87 on the 13th.

Autumn 2015 – Summary

The beginning of December heralds the start of the meteorological winter and the end of autumn which consists of the months September, October and November. The many extreme weather events that have already occurred around the world this year, including the fact that 2015 will be the warmest Globally, have been attributed to the El Niño conditions that have existed for most of the year, plus global warming. While El Niño has a less obvious effect on our weather here in the Northern hemisphere, its influence upon weather systems around the world can be long lived.

Here in Askernish, it might surprise people that this Autumn has been our driest and also our dullest. Although the enduring memory might be the storms that have been personalised by the Met Office who now name them, as much as they huffed and puffed, gusting to 67 mph and reaching wind speeds of 41 mph, they failed to surpass the winds of Autumn 2011 when the seasonal average wind speed was 11.7 mph

November 2015 – Summary

With NOAA having already announced that 2015 is going to be Globally the warmest year on record, plus the UK experiencing its highest ever November temperature, these are phenomena that seem to have passed us by here. All that we can confidently predict is that 2015 will not break any temperature records at Askernish, but it will be our windiest ever year. As for our November, it will be remembered for the Met Office naming storms for the very first time and then the first three, Abigail, Barney and Clodagh, ensuring that this was our windiest November with our first ever November gale day.

November began here as it did elsewhere in the UK with higher than average temperatures. While we did not experience the record breaking November “highs” seen elsewhere, we did record our highest ever November Minimum Temperature of 12.2°C on the 1st and then our highest November Apparent Temperature of 11.7°C on the 4th. Temperatures remained above “the norm” for the first ten days of the month, helped by persistent cloud which maintained the night time temperatures but very much restricted the hours of sunshine recorded.

Abigail, the first storm to be named by the Met Office, passed over our islands on the 12/13th leaving in it’s wake our windiest November day and our first ever November gale day on the 12th. On that day, the winds peaked at 67.0 mph, and with a maximum wind speed of 41.0 mph. The average wind speed for the day was 27.0 mph which produced a wind run 645.9 miles, all of which are records for the month of November.

There was little respite before the remnants of Hurricane Kate brought windy conditions again on 16th, and although Kate was not as bad as Abigail, this was only because it had less persistent wind speeds. Kate was quickly followed by Barney which although passing further south, it still brought some wet and windy conditions on the 17/18th.

Barney left us exposed to a more Northerly air stream which was very much colder and gave us the first taste of winter. A mixture of rain, sleet , hail and an ever present chill wind persisted until the end of the month, during which time Clodagh arrived on the 29th, again bringing strong winds gusting to 60 mph on that day.

The cloud and overcast conditions, a feature throughout the month, ensured that it was our dullest November with only 33.1 hours of sunshine being recorded on 19 sunshine days, both record lows for November. Despite the cloud, the early part of the month was relatively dry. Even so, there were 28 rain days during the month, 18 of which had more than 2mm of rain fall, another unwelcome record for November.

October 2015 – Summary

October turned out to be a contrary month being our warmest, driest and dullest here at Askernish and with warnings that hurricane Joaquin would pass our way, we experienced our calmest ever day.

High pressure continued to dominate early in the month giving rise to our highest October pressure of 1034.99 mb being recorded on the 1st. This domination continued until the 10th bringing with it dryer and calmer conditions, but it also brought its fair share of cloud.

Hurricane Joaquin was forecast to influence our weather mid-month which it did, but not in the way that everyone expected. The remnants of the hurricane passed further south through the Bay of Biscay leaving us becalmed. We enjoyed 3 days with extremely light winds and an eerie silence during which time, with a wind run of just 14.0 miles and an average wind speed of 0.6 miles, the 16th became our calmest ever day here at Askernish.

It was all change from the 19th onwards with the a series of low pressure fronts bringing more familiar weather that lasted until the end of the month, that of stronger winds, some rain and more cloud. The cloud cover was enough to ensure our dullest October while the developing rain was less than usual resulting in it being our driest. The same cloud kept temperatures higher too making this our warmest October with an average of 11.0°C.
