Conditions at Oceanside Pier in June
June: Long-Period Southern Hemi Swell, Very Few Clean Days
June brings a shift toward SW/WSW long-period groundswell, with the average period peaking at 13.8s - the longest of any month. Average height remains around 3ft (1.0m), with SW at 39%, WSW at 41%, and SSW at 8%. That is the ideal direction for the pier's southwest exposure, and sets in the 4-5ft (1.2-1.5m) range are common. However, the surf rarely gets big; only a tiny fraction of the distribution makes it above 5ft (1.5m).
Summer's onshore gradient is fully established. Ideal wind is just 4%, with W and WSW winds combining for roughly 39%, plus small but persistent onshore flow throughout the day. Most dawn patrols offer semi-glassy conditions before the sea breeze switches on, but persistent summer gloom keeps air temps at 18.1°C while water reaches 16.6°C. Rain is nearly absent at 0.15mm/day, so the main variable is wind - and June has very few of the offshore windows Oceanside needs to truly shine.
