As I've heard a lot of old timers say, "the hotter it gets, the better it gets." The bream will spawn and/or stay relatively shallow the entire summer. Don't forget about the full moon rule, as many fishermen swear by it (especially in the hottest months). With the daylight that we are having right now, the best bite will be from the break of dawn until about 9am and from about 5pm to dark. On cloudy days, they may bite all day. I believe that the full sunshine days allow them to be spooked easier, especially when fishing from the shore.
