Conditions at Avalanche in June
June: Winter Power, Winter Problems
June is the first month of true winter. The swell average increases to 7.5ft (2.3m) and the period hits 12.4s, with SW swell now leading at 26.2% and SSW close behind at 21.9%. This is serious, powerful groundswell rolling up from the South Atlantic. The catch is that only 18 percent of the time is the wind ideal for Avalanche-the lowest of the year. The wind rose is dominated by WSW at 15.8%, W at 15.8%, NNW at 12.3% and NW at 9.1%, which creates a very stormy, cross-onshore texture on the beach's NNE-facing aspect. The rare clean days happen when a high pressure ridge builds behind a cold front, pushing the wind into a lighter SSW/SW offshore flow. When that aligns with a fading W/SW swell, there are heavy, powerful waves. Air temps average 16.4°C and water 18.2°C.
