During the morning, there is usually a peak bite from late spring through early fall. When water temperatures are colder, you may not experience as good of a morning bite. During the cold times of the year, the afternoon may be much better. When water temperatures are warmer, there will usually be a good peak bite in the morning.
Yellow bass will continue to feed through the afternoons, so just because there is usually a peak bite in the mornings and evenings, that does not mean that you can’t catch them during the day. In the spring when water temperatures are warming up, this is probably the best time for fishing in the afternoons. For the rest of the year, just be prepared to go deeper when the sun is high. If you can find them, you should be able to catch some of them.
The evening bite is usually very good. There is almost always a peak evening bite from spring through fall. Find a school and you will probably catch fish until it gets dark.
Yellow bass do feed at night. Most anglers won’t go out at night to target yellow bass because they are very easy to catch during the day. However, if you want to fish for them at night, you should be able to catch them.
