Slightly different, but a few years ago myself and a friend planned to go to Bournemouth (a seaside town on the south coast) for the day. On the morning in question (this was in late May), it was cloudy and fairly chilly. Worse, the forecast was for torrential rain in the south. My friend called and it had already started raining heavily - she wondered if we should cancel our day out. I said "no, let's go for it" and we got on the train and headed to Bournemouth in lashing rain. By the time we got there - the clouds had parted and the sun was out. (It got to
80C that day!) We had the best fun ever - went on a speed boat, ate ice-creams, played air-hockey, and sat on the balcony of a bar overlooking the coast. On the way home on the train, we bumped into two of my brothers and their friends on their way back from a day out in Winchester. It was a fabulous day!
And I am very glad I didn't take any notice of the weather forecast!
