Ninth wettest March on record at Invergowrie
Spring may now have sprung, but it was our ninth wettest March on record last month, with cooler temperatures than we’ve seen in recent years.
According to our weather data, gathered at our Invergowrie site, close to Dundee, since 1954, there was 78.8 mm of rain in March, or 170% of the 30-year long-term average. A lot of that rain fell on one day – Sunday, March 12 – when a total of 28.4 mm of rainfall (~36% of the total) was recorded.
March’s rainfall compares with just 18.8 mm in February and 44.5 mm in January, making it the wettest March since 2018 (when 133.3 mm of rain fall was recorded).
Meanwhile, the daily air mean temperature was below average at 5 ºC, making it a cooler March than we have had in recent years. In fact, similar to rainfall, it was the coldest since 2018, which had a daily air mean of 3.6 ºC. However, the highs and lows swung between a blamy 14.8 ºC on Thursday, March 30, and a cool -6.7 ºC on Friday, March 10.
The sun hours for March were just above average for the time of year, at 122.4 hrs, which is 100.9 % of the long-term average.
