Rain does a few things at once: it lowers the light, can add oxygen, washes food into the water and, on rivers, raises and colours the flow. Warm rain in summer is often brilliant; cold rain in winter can chill the water and kill sport.
How fish react
Barbel & chub
A rising, colouring river after warm rain is classic barbel weather.
Tench & bream
Warm summer rain often switches them on, especially with a ripple.
Carp
Warm drizzle can be great. Heavy, cold rain often slows them down.
Pike
Heavily coloured floodwater makes lure fishing hard — deadbaits are better then.
Choosing a location
On lakes, inflows and areas where fresh water enters can draw fish after rain. On rivers in flood, fish move out of the main flow into slacks, inside bends and behind features.
Bait choices
In coloured water, use smellier and more visible baits — meat, boilies, worms, halibut pellets. Fish can't see as well so scent does more of the work.
Safety
Banks get slippery, low swims can flood and rivers can rise fast. Never fish a river that's bursting its banks, and always check the venue's notices after heavy rain.
