What constitutes a cold front?

3 posts in this topic

I know that when the temp dips overnight and the skies are clear the next morning, the bite gets really tough. How much of a drop in temps is considered a cold front? Would 5 degrees make any difference? Has anyone ever kept records?

A cold front is a rapid drop in tempature, and usually pressure, along a defined line. As long as the line is defined, the change in tempature and pressure does not matter much. The day and night tempature is usually more of a ramping down of tempatures, not a rapid drop and the pressure change is usually subtle, if any occurs at all. If the bite is harder in the morning, then there may be other factors involved. Maybe the fish have moved (most likely the problem), or the fish had a good night of feeding grin.gif. Pressure changes, rapid tempature changes, long periods of lightning, moon phases, among other natural factors must be taken into consideration when chasing fish. Fish, like other animals, sense the changes in weather, and are effected by them.

Yeah I find it funny how in the middle of summer and its 92 they say a cold front is moving in and highs the next day will be 88.....thats a cold front ?

I also laugh when listening to the NOAA weather synopsis and they say "the high temperature was 91, low temperature 85, no rain has fallen, no snow has fallen". NO KIDDING !! 85-91 and no snow. shocked.gif

      Finally making it up for our first trip of the year. Strictly walleye fishing in Frazer Bay with slip bobbers around the reefs. Appreciate any fishing reports. Thanks!

      I believe they take vets living in veteran homes around the area like Silver Bay veteran home ect

      tango loves going to Crooked lake!   Sand pines really works with you well for starting off. I don't know just because they were not busy but the kid stayed out with me and planted one by one until I told him to release them all. Golden meadows is nice as well. Do the pre buy program (I think if you buy before mid Aug) and the birds are a good price. They will flag all the birds if you want.   He still only weighs under 60lbs but I like it that way he is deadly fast and never gets tired   Cant wait to see how he does this season want to make a trip to the Dakotas at least once

      Does anybody know of a local Alexandria shop that would install a Humminbird Helix for me?

      Like Mlaker3 said... go as light as you can. The key is to try and stay vertical. It's the nature of the beast when jigging in rocks that your going to get some snags and loose some jigs.

      Thanks for all info. Even if I end up staying at the kawashiwi river campground (which I've done the past 2 years), now I at least know where to drive around and scout out some spots for next trip.

      Good advice! I appreciate it. And good to hear from you. I found fish over the weekend on reef tops with few if any bites. I should've moved on but 11-12" fish made me think better ones might come. The good fish I did find were on the sides of reefs.  I'm off the water for family business, but hoping for a good August!
