UK sea fishing does not really have an “off season” — there is always something worth targeting — but different species have clear peaks driven by water temperature, spawning patterns and bait movement. This guide covers the general pattern; check an individual location page for species specific to that stretch of coast.
The core of the winter cod season on the east and north east coasts. Cold, settled conditions after a blow often fish best — many marks in Yorkshire and the North East peak now.
A quieter transitional period. Whiting and dogfish keep marks ticking over while bass start showing in the milder south west and south coast estuaries.
Bass fishing picks up in earnest along the south and south west coasts as water temperatures rise, and the first mackerel shoals arrive inshore — a reliable, easy species for newer anglers.
Peak summer conditions. Bass and mullet fishing is at its best on the south coast, smoothhound turn up on many sandy beaches, and mackerel are abundant almost everywhere.
Often the best all-round month of the year — settled weather, warm water, and the first signs of returning cod on the north east and Yorkshire coasts as the water starts to cool.
The main winter cod run builds through this period on the east coast in particular. Rougher weather also pushes bigger cod closer to shore after a storm.
