Conditions at Dee Why Point in April
April: The Window Opens
April delivers the first reliable taste of Dee Why Point's best season. The average period lengthens to a strong 9.4s and the average swell height holds at 5-6ft (1.7m). While SSE and S swells increase significantly, a solid 38% of the total energy still comes from the optimum NE through ESE window. More importantly, the wind distribution turns more favorable than anything since late autumn: SW, WSW, W and WNW offshore flow becomes common, and the ideal wind percentage jumps to 35%. This is when morning lineups start to feel genuinely organized, with longer period pulses wrapping into the Point.
Air temperatures average 19.6°C, water remains warm at 22.3°C, and rainfall is low at 2.28 mm/day. The combination of cleaner winds, longer period and still-warm water makes April one of the most reliable surf months of the year.
