Take this weekend for example, I had a fairly good idea earlier in the week that I wouldn't be working on Friday so I started to check the forecast out to plan a couple of outings - one on Ullswater and one on the river.
The forecast for Friday was for a bright start with light winds in the morning, clouding over with the possibility of rain in the late afternoon - not very good for the lake so we went to the river.
What we got was a cloudy start, quite windy with showers, heavy at times, clearing skies late afternoon and a sunny cloudless end to the day - not quite what was forecast.
We had a decent day on the river, there were a few Large Dark Olives coming off and the odd fish rising, we stuck to the dry fly all day and did quite well.
Back to the weather - as I write this at 1630 on Sunday afternoon we still haven't had a drop of rain this weekend, not that I want any but as a fisherman trying to plan a day out on river or lake based on the forecast, it would be nice if they were a bit more reliable.
