A lack of warm walking jackets
may catch out many people when weather changes suddenly - even, it would appear, climate experts.
The group of 14 delegates from national parks in Italy and Slovenia came to the Lake District last weekend to see how the national park authority manages issues of climate change and discovered how much things can vary as the hot spell suddenly ended.
Becky Willis, the climate change advisor for the authority said the delegates suddenly became "really cold," having turned up when the temperature had soared to 27 degrees C - a situation that did not last long as the mercury plummeted to 15C.
"Our visitors weren't really dressed for our normal October weather," she observed.
Visitors to the Lake District in the next few days may find it very wise to have good walking jackets
, with the Met Office forecasting plenty of rain, hill fog and windy conditions on the fells.
