Conditions at La Jolla in April

April: Peak Spring Quality

April is statistically the cleanest month of the year at La Jolla. The ideal wind percentage peaks at 64 percent, while the average wave period increases to 13.7s, placing the surf firmly in the powerful long-period category. Swell is heavily dominated by SSW (61.3 percent) and S (21.3 percent), with most heights in the 3-5ft (1-1.5m) range and a significant portion reaching 5-6.5ft (1.5-2m). This creates consistent, well-spaced lines in the 4-5ft (1.2-1.5m) range, with occasional larger sets.

The wind pattern is much less aggressive than winter: SW-WSW flow becomes more frequent, N/NNE winds weaken, and the lighter morning breeze is often ideal. Air temperatures average 27.1°C, water temperature is 28.7°C, and precipitation is still modest at 0.20mm/day. For an east-facing beach that rarely sees its preferred west-northwest swell, April is the month when the summer-style southern swell and clean offshore winds align most often.
