Yesterday evening, having climbed Ben Hiant with the rest of us in the morning, our daughter and son-in-law felt that they had not yet had enough exercise, so decided to go for a swim. The Diary, ever keen to record such events, went down to the beach with them and watched as they set off in the gloom across the Sound of Mull towards Tobermory.
After about twenty minutes they returned. But, instead of chattering teeth, blue skin and gasps for breath, there was cries of "That's so.... warm!"
Sea temperatures in this area tend to reach their maximum in September and are still high in October. The current temperature is about 12C, warmer than the daytime air maximum, and certainly higher than the evening air temperature when the two intrepid swimmers left the sea.
