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.

Apologies for the briefer than usual summary. This was due to the station being unmanned throughout the month.

Winter 2015-16 – Summary

While the UK recorded its warmest winter, it was a phenomenon that passed us by. Temperatures here at Askernish were “average” with a mean (1 minute) temperature of 6.2°C for the winter period.

The only other statistics of note were that there were only 34 days when the sun shone, the fewest recorded in winter, 21.8mm of rain fell on the 28th December making it our wettest winter day, and the maximum pressure of 1031.94mb on the 15th February was the lowest maximum recorded for winter.

Apologies for the shorter than usual summary. This was due to the station being unmanned for most of the winter period.

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

Apologies for the briefer than usual summary. This was due to the station being unmanned throughout the month.
