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.

Summaries for the three months that constitute Spring precede this summary on the blog.

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.
