Monday was such a contrast to previous days as the unpleasant northeasterly wind brought much cloud from the North Sea for most of the day. During the late afternoon there was a little brightness with just 5 minutes of sunshine.
Not surprising to find that temperatures fell away with the warmest part of the day at 09.55 giving a maximum of 18.2C. This was 2C below average, which was 7C down on the Sunday maximum and dropped away a couple of degrees for most of the day.
Thicker cloud was driven in overnight by a freshening northeasterly, gusting to 20mph, so that the thermometer dropped away to a minimum of 11.3C, still 1.3C above average.
Tuesday arrived with thick cloud lowering over the Marlborough Downs and light drizzle in the air but not measurable.
Update at 17.50: cool day as northeasterly meant temperatures for most of the day no more than 13C but late brightness lifted to 16.5C at 16.35 when average is 20C.
