I have known for a while that the barometric pressure affects fishing, but I always forget how. Every time I want to use the barometric pressure to figure out how fishing will be, I had to spend a while researching the subject. NOT ANY MORE! I put together a cheat sheet that I will start referring to.
Here it is:
- High Pressure (30.50 +) = Clear Skies = Fishing Medium to Slow = Fish slowly in deeper water or near cover.
- Medium Pressure (29.70 – 30.40) = Fair Weather = Normal Fishing = Test lures, baits, and techniques to see what works.
- Low Pressure (29.60 -) = Cloudy/Rainy Weather = Fishing Slows = Fish slowly in deeper water or near cover.
- Rising Pressure = Improving Weather = Fish Slightly Active = Fish slowly in deeper water or near cover.
- Stable Pressure = Fair Weather = Normal Fishing = Best time to test lures, baits, and techniques to see what works.
- Falling Pressure = Degrading Weather = Best Fishing = The fish will attack anything you throw at them. (well, pretty much)
So, what is the best barometric pressure for fishing? Answer: When it’s between about 29.90 and 30.90 and the pressure is rapidly falling. This is when you will find the fish most active and feeding.
You could check the barometric pressure online, but I prefer to have my own hand-held barometer, so I can keep an eye on the pressure in real-time. That way I can see exactly when the pressure starts moving in a favorable direction, and still make it to the water in time for some awesome fishing.
