Traveller notes on Keswick in December
Other months in Keswick
Keswick's forum is upfront that June can go either way — hot and sunny some years, cold and wet others — and that the Lake District is one of England's wettest regions regardless, with conditions on the fells changing within minutes. Regulars still rate it a good month: long daylight into nearly 10pm leaves plenty of time for a fell walk after dinner.
