Conditions at Sealion Cove in April
April: Best Offshore Reliability of the Year
April eases to a 2.2m (7.2ft) average with a period of 10.8s, but the wind picture turns in your favor with 43% ideal offshore flow - the highest of the year. The swell direction pivots further south: SW rips 22.4%, WSW 18.4%, and SSW 13.6%, while the pure W-NNW sector collapses to about 9%. That said, the mix still carries enough power for a solid head-high to overhead day, especially when a long-period W groundswell lines up.
Water is a touch warmer at 6.3°C and air temps climb to 3.8°C on average, while rainfall drops to 4.11mm/day. April is a good month to find fun, rippable waves without the brutal cold of winter. Just be aware that the onshore NW wind is becoming more common in the afternoon, so sunrise will almost always be the call.
