A Met Office spokesperson said: "Southeast England could see maximum temperatures in the high teens, perhaps touching 20 Celsius.
"The extent and degree of warmth will be affected by how much cloud cover there is which is difficult to forecast accurately three days ahead, however there will be some decent bright or sunny spells.
"The warm air may hang on across the south where, if sunshine allows, it could turn very warm with temperatures getting close to the UK temperature record for November of 21.7C.
"Record breaking or not, this weekend provides plenty of opportunities to get out and shake off those cobwebs."
