The Best and Worst Times to Go Fishing

By Alex Clayton · Updated 23 October 2026

You drive an hour, set up on a bright, flat-calm afternoon and watch a motionless float until the light goes. The bait was fine. The timing wasn’t.

For most UK coarse and predator fishing, the best time to fish is the first two hours of daylight or the last hour into dark, on a mild, overcast, breezy day with a steady or gently falling barometer, from spring through autumn. The worst times are just as predictable: the day or two after a sharp cold front, bright still middays under high pressure, peak summer heat, rivers in heavy flood, and near-freezing water if you’re after carp.

The six steps below work out the best time to go fishing in the order you should decide it. Rules come first, because England, Wales, Scotland and Northern Ireland don’t share them.

Step 1: Check the Close Season and Licence Rules for Your Nation

In 2019 the Environment Agency asked anglers whether England’s river close season should go. 49.2% of respondents backed scrapping it and 38.8% wanted it kept, and the EA kept it anyway. Rule out what you can’t legally fish first.

Nation	Coarse fish on rivers	Stillwaters and canals	Trout note	Official source
England	Closed 15 March to 15 June inclusive on rivers, streams and drains	Most open all year; some, including certain SSSIs, still close	Trout and salmon seasons set by local byelaws	Environment Agency, GOV.UK
Wales	Open 16 June to 14 March	No close season, except certain SSSIs	Non-migratory trout on most rivers: 3 March to 30 September	Natural Resources Wales
Scotland	No annual or weekly close times	No close times	Brown trout closed 7 October to 14 March; salmon close times vary by district, and no salmon rod fishing on Sundays	Scottish Government
Northern Ireland	Generally no close season	Generally no close season	Game seasons apply when you coarse fish on game waters	nidirect

The close season protects fish that are preparing to spawn, spawning or recovering. In England, fishing for coarse fish on a closed river is an offence under the EA’s national byelaws, and you still need a rod licence for the waters that stay open (Environment Agency).

Local byelaws and fishery rules can be tighter, so check with the EA, Natural Resources Wales, the Scottish Government or district salmon fishery board, or nidirect, then the fishery. Our guides to close seasons across the UK and rod licence rules cover the detail.

You should now know which waters near you are open this week. In the river close season in England or Wales (mid-March to mid-June), start with a stillwater or canal.

Step 2: Pick the Best Time of Year for Your Target Species

Why is a freezing January morning decent for pike and dire for carp? Water temperature, which matters more than the hour.

Treat the temperature at the depth you’re fishing as your real calendar. Angling-press guidance (not peer-reviewed) puts carp as generally unwilling to feed below about 4C, with a spring rise into double figures over several days a good sign (Angling Times). Pike and perch stay relatively active in cold water, which is why pike and chub are classic winter targets (Fisheries.co.uk).

If you want one answer to the best time of year to go fishing, it’s autumn: the water still holds summer heat and many species are feeding up.

When each species is usually at its best (general UK guidance; it varies by water and by year):

Species	Usually best	Why	Watch out for
Pike	Autumn and winter	Cold-tolerant	Hot weather
Perch	Autumn and winter	Active in the cold, shoal on structure	Bright days push them deep
Bream	Late spring to autumn	Shoal up as water warms	Sudden cold snaps
Carp	Late spring to autumn	Feed hardest when warm	Near-freezing water
Tench	Late spring and summer	A warm-water fish	Barely feed in winter
Roach	Autumn and winter	Feed in cold, clear water	Heavy floodwater on rivers
Chub	Autumn and winter	Feed in cold rivers	River close season in England and Wales
Brown trout	Spring to early autumn	Open seasons fall in the warmer months	Dates vary by nation (Step 1)

On English and Welsh rivers, coarse fishing opens on 16 June. On Windermere I keep after pike and perch right through the colder months, long after the bream have gone quiet. See our month-by-month seasonal guides and winter pike fishing guide.

You should now have a species and a season. Best for: winter pike, perch, roach and chub. Skip if: you want carp or tench in near-freezing water.

Step 3: Choose the Best Time of Day to Fish: Dawn, Dusk or Night

Moving the same session two hours earlier costs nothing and is often the biggest single change you can make. Light is the reason, according to Angling Times guidance (Angling Times).

The first two hours of daylight are often the most productive. Oxygen levels recover after the night and natural food such as daphnia and bloodworm becomes active, so fish move and feed. Arrive in the dark and be fishing as it gets light, not still tackling up.

Dusk is the predator angler’s window. Pike and perch are often at their best as light fades, and in my experience on Windermere the last hour of light is the one to be on the water for both.

Night fishing earns its place in summer, when bright or hot days push fish into cover. Check the fishery allows it first, using our guide to night fishing rules.

Midday is usually the weakest slot on bright days. Deep winter flips that: the warmest part of the day is often the best time of day to fish.

Time window	Why it works	Typical targets (general)
Dawn, first two hours	Oxygen recovering, natural food active	Most coarse fish, carp, tench
Dusk, last hour	Fading light suits hunting	Pike, perch, chub
Night	Cooler and darker in summer	Carp, bream, tench
Winter midday	Warmest water of the day	Roach, chub, perch

For more ways to make a session count, see our practical fishing tips.

You now know when to arrive and when to pack up. Choose dawn for general coarse fishing and dusk for predators.

Step 4: Read the Weather: Cloud, Wind, Pressure and the Moon

One well-known fishing guide says a fast change in air pressure sets off a feeding spree, then says the same change makes fishing hard. It can’t be both. Read the whole forecast instead of one number.

Cloud. Cover cuts the shadows cast by birds and anglers, so fish are less wary (Angling Times). A grey, mild day is a good day.

Bright sun. Bright sun with high pressure tends to put fish off, especially in low, clear rivers. Rudd are the noted exception.

Wind. A mild breeze puts a ripple on the surface and breaks up the light, which can make fish bolder. A gale you can’t present a bait in is another matter.

Pressure. Watch the trend over a day or two, not the number on the barometer. Most anglers favour a steady or gently falling barometer ahead of mild, unsettled weather, and most dislike a sharp rise behind a cold front. That’s angler consensus rather than proven science, and our guide to air pressure and fishing looks at it in detail.

The moon. Solunar tables and moon-phase charts are everywhere, but we found no solid evidence behind them, only automated calendars. Treat them as a tiebreaker at most. Our moon phase fishing guide covers what’s claimed and what isn’t.

For the full picture on how the weather affects fishing, see the weather hub. You should now be able to call a forecast go, maybe or adjust.

The verdict: overcast, mild and breezy beats bright and calm, and a steady barometer beats a sudden jump. Ignore the moon unless everything else is equal.

Step 5: Spot the Worst Times to Go Fishing Before You Set Off

A clear blue sky and a crisp, still morning look perfect, and they’re often the worst time to go fishing. Some red flags only mean slow fishing. Others put fish welfare or your safety first.

Condition	Why it’s poor	What to do
The 24 to 48 hours after a sharp cold front	Widely reported as slow while fish adjust to the drop in temperature	Fish finer and slower (Step 6)
Bright, still, high-pressure middays	Fish are wary and drop back, especially in low, clear rivers	Fish dawn or dusk instead
Peak summer heat	Hot, sunny weather can trigger algal blooms that cut dissolved oxygen	Fish early or late, use less bait
Rivers in heavy flood	Fast, debris-laden water and unstable banks	Stay off undercut or flooded banks
Thunderstorms	Carbon rods conduct electricity	Pack up and get off the bank
Near-freezing water, for carp	Below about 4C carp are generally unwilling to feed (Step 2)	Switch to pike or perch

Heat needs the most care. The Environment Agency asks anglers to minimise bait in hot weather, take extra care with pike, barbel, trout and salmon, and avoid photographing fish out of the water (Angling Times). If you see fish gasping at the surface or dying in England, report it to the EA incident hotline on 0800 80 70 60. In Wales, Scotland or Northern Ireland, contact Natural Resources Wales, SEPA or the Northern Ireland Environment Agency instead.

Floods are a safety call first. When a river drops back, our guide to fishing after floods covers where the fish go.

Don’t forget the legal worst time from Step 1: a closed river.

You can now tell slow-but-fishable from leave-it. Fish it if it’s a cold front, a bright day or a cold snap. Skip it if there’s thunder, a river in heavy flood or fish visibly in distress.

Step 6: Adjust Your Tactics Instead of Cancelling the Session

When it’s slow, cutting the feed is usually a better move than adding more. Most poor conditions from Step 5 are fishable if you scale down, slow down and move.

Cold front or bright day: drop a hook size or two, step down to a lighter hooklength and fish smaller baits. Feed little and often, and fish deeper, in shade or tight to cover.
Heat: move your session to dawn and dusk, use less bait as the EA advises, keep fights short and keep fish in the water.
River close season in England or Wales: switch to an open stillwater or canal, checking local byelaws first.
Coloured, rising river: fish slacks and inside bends out of the main flow, and only from a bank you trust.
Deep winter: switch to pike or perch, fish the warmest hours and slow everything down. See our winter fishing guide.

In cold water on Windermere I slow a drop-shot right down near structure, barely moving the lure, because perch won’t chase far. Our guide to drop-shot fishing explains the set-up.

By now you should have a fallback plan for any forecast. If the forecast is against you, start by fishing finer, feeding less and moving to the shade or the deepest water you can reach.

Frequently asked questions

What is the best time of day to fish in the UK?

The first two hours of daylight and the last hour into dark are usually best. Dawn brings recovering oxygen levels and active natural food, while dusk suits predators such as pike and perch. Summer nights can outfish both, and in deep winter the warmest part of the day is often the best time to fish.

Can you fish rivers in the close season?

Not for coarse fish in England, where rivers close from 15 March to 15 June inclusive. Welsh rivers are open to coarse fishing from 16 June to 14 March. Stillwaters and canals are generally open in both, except certain SSSIs. Scotland and Northern Ireland generally have no coarse close season. Check local byelaws, and carry a rod licence.

Is it worth fishing in the rain?

Yes, if it's mild rain under cloud. Grey, drizzly days often fish well because fish are less wary in low light (see Step 4). Heavy rain that floods a river, or rain with thunder, is different: stay off flooded banks and pack up (see Step 5).

Does the moon affect fishing?

No solid evidence shows that it does. Solunar tables and moon-phase charts are automated predictions, and they remain unproven. Plan around water temperature, light and weather first, and use the moon as a tiebreaker at most. Our moon phase fishing guide covers the claims in more detail.
