As a fishing youngster in the 1950's I went fishing with only scant regard to weather. I was limited to weekends as a schoolboy and the only way I could get out to fish in anything other than my local lake was to go out on club outings. One booked a seat on the coach and you turned up, regardless of weather, to fish a match, so if it rained all day, or snowed or was freezing cold you just got on with it. No umbrella, no tent, little warm clothing of merit, no nothing in fact, apart from a WW2 cape and S'wester to keep off the rain, which they did, until another cast was necessary!
Fortunately, I didn't ail at all, despite sitting in a damp coach for the two hours at least it took to get home, so when I think about 'worst weather' nothing really stands out. Let's face it, how often do we fish in 'ideal' conditions' anyway? It's either too cold, too hot, too wet and everything in between. Most of us go fishing regardless of the elements and it has always been that way for me, but I have been caught out by sudden/continual torrential rain without a brolly which soaked everything and snowstorms where the the float was hard to see and the fishing bag disappeared beneath the onslaught.
And it hasn't always been cold weather either...I well recall going to fish the Vaal Dam in S. Africa (300 odd sq miles surface area and few trees) with a pal and ending up taking shelter from the sun in a cattle shed because of the heat. Heat exhaustion/dehydration was the main issue and it took many days to recover fully. I didn't do that again in a hurry!
These days I tend to be more choosy around weather, but that doesn't mean I don't go. Today we have a heavy frost but it looks like a very nice day in prospect, so I put the bait back in the fridge and will go walking instead. Tomorrow looks like a very wet day and much better conditions for roach fishing, so that is when I will be out. A faff with umbrellas for sure, everything will take more time and all will need drying out eventually, but go I will!
Generally speaking, inclement weather is par for the course in the UK, so I never quite understand those who pull back from a wet, breezy day and sit at home instead. Wouldn't do if we were all the same, now would it?
