Climate

The Lake District's location on the northwest coast of England, coupled with its mountainous geography, makes it the wettest part of England. The UK Met Office reports average annual precipitation of more than 2,000 mm (80 in), but with considerable local variation.

Although the entire region receives above-average rainfall, there is a wide disparity between the amounts of rainfall in the western and eastern lakes, as the Lake District experiences relief rainfall. Seathwaite, Borrowdale is the wettest inhabited place in England with an average of 3,300 mm (130 in) of rain a year, while nearby Sprinkling Tarn is even wetter, recording over 5,000 mm (200 in) per year; by contrast, Keswick, at the lower end of Borrowdale, receives 1,470 mm (58 in) every year, and Penrith (just outside the Lake District) only 870 mm (34 in). March to June tend to be the driest months, with October to January the wettest, but at low levels, there is relatively little difference between months.

Although there are gales in the sheltered valleys on only five days a year on average, the Lake District is generally very windy: the coastal areas have 20 days of gales, and the fell tops around 100 days of gales per year. The maritime climate means that the Lake District has relatively moderate temperature variations throughout the year. The mean temperature in the valleys ranges from about 3 °C (37 °F) in January to around 15 °C (59 °F) in July. (By comparison, Moscow, at the same latitude, ranges from −10 to 19 °C (14 to 66 °F).)

The relatively low height of most of the fells means that, while snow is expected during the winter, they can be free of snow at any time of the year. Normally, significant snowfall only occurs between November and April. On average, snow falls on Helvellyn 67 days per year. Snow typically falls on 20 days of the year in the valleys, with a further 200 days with some rain, and 145 completely dry days. Hill fog is common at any time of year, and the fells average only around 2.5 hours of sunshine per day, increasing to around 4.1 hours per day on the coastal plains.
