Conditions at Killer Point in June
June: Small but Frequent Windswell
June sees the summer pattern fully entrenched. The average swell height slips to 1.6m (5.2ft) and the period bottoms out near 8.4s. Swell direction is now overwhelmingly NNW, at 78.9%, with NW only 12.3%. What this means at Killer Point is a constant supply of short-period northwest windswell, often in the 1-2m range, rather than true groundswell. The waves can be fun on a good day, but they lack the power and depth of winter.
Winds are tough. Ideal offshore conditions occur only 14% of the time, the lowest of the year. The semi-permanent Azores High pumps a relentless NNW flow, with NNW 35.7%, NW 30.3% and WNW 8.2% dominating. This leaves the spot frequently onshore, though the lighter NW/N winds in the morning can offer a clean session before the afternoon breeze. Summer warmth arrives: air 21.1°C, water 17.9°C, precipitation only 0.10mm/day.
