BBC weather website was quite clear; Heavy Rain all day. I packed waterproofs, and deliberately omitted dark glasses, sunscreen, for the trip from Derby to the National Watersports Centre at Holme Pierrepont (20 miles each way).
About 5 drops of rain at 0830; completely dry for the entire rest of the day. Sunshine off and on, but only light cloud cover.
How can they get the forecast that far wrong?
