Temperatures at California Beaches in April. Typical temperatures for beaches along the Pacific Ocean in California during the month of April are listed below. The tables give monthly averages of daily maximum and minimum air temperatures for each location and, where available, the month's average ocean temperature.
The annual spawning run of the official state fish, often called the âsand bass,â occurs during the spring and is perhaps best described as a âfish frenzy.â White bass move in large schools to spawn, and anglers who fish at the right time can end up with near constant angling action as well as a stringer full of fish.
Spawning takes place from November through March, peaking in January. The adults tend to congregate at nesting sites. The eggs are laid in large masses on cleared rocks. The individual nest is guarded by the male who will drive away any intruder. A 5 pound female will lay an average of 66,000 eggs and a 23 pound female, 152,000.
