June: Southern Hemi Swell Meets Westerly Chop
June marks the official start of Oceanside's summer surf pattern. Average swell height drops to 1.0m (3.3ft), but the direction mix is excellent: SW dominates at 38.8%, WSW at 41.0%, and SSW at 7.8%. These are long-period Southern Hemisphere groundswells radiating into the Southwest-facing beach, with an average period of 13.8s. The problem is size - most waves are in the 2-3ft (0.5-1m) range, with a secondary peak in the 3-5ft (1-1.5m) range and almost nothing overhead.
Wind quality is poor. Ideal offshore flow happens only 4% of the time, and W winds at 19.9% plus WSW at 19.4% create persistent afternoon chop. There are occasional early-morning glass-offs, usually around dawn before the Pacific High pumps the onshore flow. Water temp is 16.6°C (61.9°F), air temps reach 18.1°C (64.6°F), and rain is basically nonexistent. If you can find a clean early window, the long-period SW swell is fun, rippable, and often surprisingly user-friendly.
