Conditions at Avalon in April
April: Autumn's Alignment - Clean SE/SSE Groundswell
April is where Avalon starts to turn on. Ideal offshore wind jumps to 34%, the average wave period rises to 9.2s, and the swell distribution spreads across E 16%, ESE 19%, SE 21% and SSE 21% - all favorable directions for this stretch of coast. The S percentage increases to 8%, reflecting the first solid winter frontal activity in the Tasman Sea, and this mix means more swell reaching the beach with better shape. The average height remains at 1.4m (4.6ft), but over a quarter of observations fall into the 1.5-2.5m (5-8ft) category, mostly from SE/SSE. W/NW/NNW winds supply clean, glassy surfaces, and the lower humidity adds to the appeal. Air temp cools to 18.4°C, water temp is 22.0°C, and rain averages 2.34 mm/day. This is the month when the autumn lineup starts feeling serious.
