LONDON — Two days of unseasonable sunshine in Britain this week have resulted in more than the shedding of hats, scarves and winter coats: They have also brought the highest temperatures ever recorded in the country in winter.

Temperatures peaked on Tuesday at 21.2 degrees Celsius (70.16 Fahrenheit) in Kew Gardens, London, the hottest February day in Britain since records began in 1910, according to the Met Office, the national meteorological service.

Warmer than an average summer day in Britain, the record set on Tuesday ended a short-lived run for Porthmadog, Wales, which had laid claim earlier in the day with a high of 20.8 degrees Celsius (69.44 Fahrenheit).

February’s new maximum temperature record was also snatched from the rural community of Trawsgoed, Wales, which had set a record on Monday with a high of 20.6 degrees Celsius (69.08 Fahrenheit).
