Your February weather guide
February is a reasonable month for a UK trip if you are happy with cold weather and flexible plans, but it is not a good choice for warmth. Country averages of 8°C by day and 3°C at night call for proper winter layers, while 12 rainy days make waterproofs useful. Cornwall has the edge for milder temperatures; London is slightly cooler but has fewer rainy days. Choose based on your tolerance for cold evenings versus wet weather.

All 2 places we track in United Kingdom, ordered by daytime high.

Within 1.5°C of United Kingdom's February daytime average: Thassos (10°C, sea 12°C), Pula (10°C, sea 10°C), Verona (10°C), Milan (9°C), Tokyo (9°C, sea 13°C). See the full ranking for February.
Cornwall is the warmer choice between these destinations, averaging 9°C by day and 5°C at night. That makes it a better fit if you want less chilly evenings, though it is still coat weather rather than anything approaching summer. The catch is rain: Cornwall averages 13 rainy days, compared with 10 in London. London reaches 8°C during the day, so the daytime difference is modest, but its 2°C nights make warm evening clothing more important. For a trip built around outdoor time, neither offers dependable dry weather. Pick Cornwall for milder nights, or London if fewer rainy days matter more.
Pack for cold, potentially wet days rather than relying on a bright forecast. A warm coat, layers and waterproof footwear give you more flexibility when rain interrupts outdoor plans. With average sunshine of 2.8 hours a day, February is not a strong choice if long sunny spells are central to your holiday. Keep your outdoor plans movable and leave room to spend time indoors when conditions are less inviting. The sea averages 9°C, including in Cornwall, so do not expect comfortable casual swimming. This month suits travellers who can enjoy a winter break without needing warmth, sustained sunshine or much time in the water.

The country average is 12 rainy days, with 13 in Cornwall and 10 in London. Rain is frequent enough to affect outdoor plans, so bring waterproofs and stay flexible. These figures do not mean it rains throughout each affected day.
Not if you want comfortably warm water. The average sea temperature is 9°C, including in Cornwall, while daytime air temperatures are also low. February is better suited to plans that do not depend on spending time in the sea.
