A new record has been set for the UK's warmest February day.
The thermometer reached 20.3C (68.5F) at Trawsgoed in Ceredigion, west Wales, beating the previous record of 19.7C (67.4F) recorded in Greenwich in 1998.
Meteorologists said it was the first time the temperature has exceeded 20C (68F) in winter.
Announcing the new record, the Met Office tweeted: "It's reached 20.3 °C at Trawsgoed, Ceredigion making it the UK's warmest February day on record. It's also the first time we've recorded over 20 degrees in winter."
The unseasonably warm weather comes a year after the UK and Ireland were hit by a period of icy conditions which became known as the Beast from the East.
Forecasters said the current conditions also brought with them the risk of overnight frosts in some places and patchy mist and fog in the mornings.
The warm spell is set to continue tomorrow and on Wednesday but it will become less mild and unsettled from Thursday with some heavy showers possible, according to the Met Office.
