The 8.4 hours of sunshine on Monday made it the second sunniest day this month but the steady flow of much cooler air from the north limited the temperature to a maximum of 12.4C. This was 5.4C down on the Sunday peak and 2.3C below average.
The wind had veered into the north on Sunday night as the high pressure eased westwards to centre over the Atlantic.
It was another dry day, the sixth consecutive dry day with the rainfall total still 39.8mm when the October average is 84.8mm.
Although clear skies initially overnight that allowed the thermometer to fall away to a minimum of 3.1C at 23.3, a thin veil of cloud stopped the fall so that at 08.00 today the thermometer read 6.4C.
Tuesday arrived with the thin cloud persisting and blotting out any possibility of sunshine when readings were taken at 08.00.
Update at 17.50 on Tuesday: the modest backing of the wind from the north into the north west gave a slightly higher maximum of 14.6C, average for October. There was less sunshine, 5.8hours, due to more cloud often quite thin.
