Night time temps more important than daytime
i am convinced that night time temperatures are more important than daytime concerning when fish spawn or become more active, especially in shallow water depths...daytime temps can get into the 70s, but if the night time temps are still in the 30-40 range the fish won't be as active...but if the night time temps are in the upper 40s to 50s,,,and daytime in the 70s...this will trigger the fish to spawn and become more active..of course this is just a theory...not proven but observed by many days on the water..so i get excited when those warm days and cool, not cold nights get here, because i know the action is going to be great..
to take it a step further
Bobfish is pretty much right on at least as for down here in south louisiana.
the warm nights are important for a couple of reasons, first off the water temp doesnt drop as much so that means higher water temps the following day. Also of at least as much importantance when the temp is higher at night in spring it means the return of clouds, wind, lower pressure, humidity, and that we are moving away from a front as probably approaching another. This week is almost the perfect set up.. days like Sunday and Today and tomorrow with high temps near 70 that will warm the water but are bright bluebird days with fairly tough fishing. then toward the end of this week the pressure will drop, humidity etc return and on top of that full moon friday. nighttime temps will still be little cool but fishing thurs til mon or so is should be super in our area(hope to get out about four of those days to find out). The funny thing about bass and sacalait fishing (especially in spring) is that people will say dont you wish you were fishing on a day like today(bright, high pressure) my response is always no I want to work today and fish on the cloudy, windy ,humid day that happens a couple of days later. On another note my dad caught 11 today so it wasnt terilble but slow(all males not suprising this close to full moon) females should return by end of week
By far the best days are those night when the front is approaching and the night temp is 60-62 On those days you are almost guaranteed a good day during the spawn. I could go on and on but think I'm done
