Daytime temperatures in Maidenhead fell to their lowest in two months yesterday.
The temperature reached just 12.2C on a cold and wet bank holiday Monday.
Meteorologist and Maidenhead resident Dr Roger Brugge said this was 6C below the average for the time of year and the lowest daytime maximum temperature since the end of March.
Persistent cloudy skies meant there wan no bright sunshine recorded all day and there was also 9mm of rain.
"Since my daily local records began in 1988, the only late May Bank Holiday Monday to be colder was that of 2007 when the temperature only reached 11C," said Dr Brugge.
"At least Sunday this year was a sunny one with over 12 hours of bright sunshine."
The forecast for this week suggests the unsettled weather will continue with cloud and rain spilling across Berkshire at times from the east.
Daytime temperatures are expected to be higher than on Monday and closer to the normal for late May.
