Living in New Jersey it takes a lot of daylight/sunlight to warm up the waters after iceout. The warmer southern winds blow the warm water in a direction of its choice for that day. The waters swirl and mix with the colder water . On an average -the water temps warm faster to where the warmer water is blowing by 3-5 degrees. . The flats near that area produce first. Try to be near the shorelines where the sun has been beating on as well.I have fished early spring at night for over 30 years. The scret is a wide wobble with slow steady retrieve. The buzzbait will do it a little later on as water temps are in the low 50's The colorado bladed spinnerbaits work well but for the real early stuff the wide wobble swimbait is the top producer. Im not talking your average flat sided swimbait with a typical tail on it. Im talking wobble/thumper stuff. This wide wobble swim bait on a shake 2 head had been my top producer. I would cast paralell the shorelines til I found what depth they were using., Like I said just slow /staedy thump thump thump. The flats near deep water produced best. This is not to push product but this is the swimbait/fatshad. It has a different action than the other swimbaits. remember -slow and steady-.Just turning the reel handle till ya feel the rod tip vibrating.. Hold on -the big fish are hungry at that time of year.
