Covid-19 Pandemic to one side, I thought I'd post a summary covering our weather for March 2020. The first thing to say is that it eventually turned out to be much drier than February. However, as February was the wettest month of the last 10 or so years that isn't saying a great deal. March started off a bit like the previous several months with low pressure systems coming in off the Atlantic Ocean bringing gale force winds and heavy rain.

The middle of March saw a distinct change in the weather as high pressure began to dominate bringing us a much drier second half of the month.

By the time the end of the month arrived, we'd only had 30.0mm of rainfall, all of it falling in the first half of the month. That's below average for March, with only 2012 and 2011 having less rainfall over the last 11 years, but I for one aren't complaining as it has helped dry out the allotment.
The last week of March was been on the cool side and strangely we've had colder days in March than we had through the winter months. March has the coldest days of 'winter' and the warmest day of the year on 24 March when the thermometer hit a very pleasant 19.5°C. It wasn't a particularly long spell of fine weather and it also coincided with the start of the lockdown due to Covid-19. In the end the final average for the month turned out to be just that about average.

We've had more frost in March than January and February combined, although I think that is due to those two months being exceptionally mild rather than any unusually cold March nights.

Everything seems topsy turvy and unnatural these days, and there is a meteorological oddity that must be added to the list:
March was cold than January in Seattle this year."

I'm not sure how unusual it is here for March to be colder than January but the reason for our mild January and February has been put down to the record breaking Polar Vortex through winter. That's driven strong westerly winds all through winter stopping the development of any high pressure systems which bring us cold weather in winter.
