The activity score
A day is rarely all good or all bad. WeatherDuck scores every hour from 0 to 10 — wind weighted hardest, then rain, then cloud — so you can see the three good hours hiding inside an average-looking day.
A typical Tuesday
ExampleSame day, same place — but a 5-point swing between 10am and 4pm. That gap is the whole point.
Also included
The hours after sunset, and the state of the ground when you get there.
Cloud, moonlight and genuinely useful darkness — plus the wider night-sky outlook before you commit to a late one.
Check rainfall from nearby Environment Agency, SEPA and Natural Resources Wales stations, plus clothing guidance. Rain gauges and rainfall history are public; ground dryness is available with a free account.
