Why fish feed before a cold front
Falling pressure often switches fish on, and the clear cold day afterwards often switches them off. Here is what to do about it.

The pattern most anglers notice
Ask anglers about weather and many will tell you the same thing: the hours before a front arrives can be excellent, and the bright, cold, high-pressure day that follows can be hard work.
What is actually changing
A front brings several things at once, and they are easy to confuse:
- Falling air pressure in the hours ahead of it
- Cloud cover building, which cuts light at the surface
- Wind picking up, pushing surface food to one bank
- A temperature drop after it passes
Fish respond to all of these, not just the barometer. Cloud and wind alone will often bring fish up and out of cover, because low light makes them harder to see from above.
How to fish the two halves
Before the front — fish it hard. Cover water, fish a little more actively, and concentrate on the windward bank where surface food collects. This is the window worth rearranging your day for.
After the front — slow down. Clear skies and a sharp temperature drop tend to push fish deeper and make them lethargic. Go smaller on bait, fish slower, and target the deepest comfortable water you can reach. Midday is often better than dawn, because the water has had time to warm.
A caution
Weather shifts the odds; it does not decide the day. Treat pressure as one factor among structure, season and water temperature — not as a forecast of whether you will catch.
