It’s going to get increasingly warm by the middle of the week so be prepared.
There will be increased UV and pollen levels so precautions are advised.
The sun now is as strong as it is at the end of August so fair skin can burn in about 30 minutes without protection.
Northants meteorologist Paul Barber from Forecasts4u has provided this forecast exclusively for the Northants Telegraph.
Monday: A cold and bright start to the day with plenty of sunshine but this sunshine will become increasingly hazy as cloudier conditions spread up from the south although most places will remain dry.
Maximum temperatures in the range of 15°C to 16°C, feeling warmer than the weekend with lighter winds.
Tuesday: Early mist, fog and low cloud will readily clear to leave a fine and dry day across the county with plenty of sunshine developing.
The sunshine will help lift temperatures up to highs of 19°C or 20°C with light to moderate south-westerly winds.
