Conditions at The Alley in June
June: Peak Winter Clean
June brings the most reliable conditions of the year. Ideal wind percentages peak at 66 percent, the average period reaches 8.9s, and while the average swell height eases to 1.0m (3ft), the quality jumps. ESE (25.7%), E (22.1%), and SE (21.2%) swells combine with SSE (12.3%) energy to keep the bank alive. Winter high pressure systems park over the mainland and generate S (18.1%), SSW (15.9%), SW (8.4%), and WSW (7.0%) winds, exactly the offshore quadrant The Alley needs. Air temps drop to 19.4°C, water temps to 21.7°C, and precipitation runs 3.07 mm/day. Expect clean, punchy 2-4ft (0.6-1.2m) surf with occasional larger pulses when a vigorous low pushes deeper into the Tasman Sea.
