Conditions at Sunrise in April
April: The Window Opens into Autumn Gold
April is when Sunrise starts to wake up. The average swell height remains 1.8m (5.9ft), but the period jumps to 9.9s and the S/SSE components become more prominent (SSE 19.1%, S 14.6%). While S/SSE aren't in the bull's-eye window, their longer period allows them to wrap into the ESE-facing beach and maintain shape. The E/ESE/SE window is still very active, with 16% E and 16% SE. A major shift is the wind: the NE trades drop to 14.7%, while the west/northwest offshore quadrant expands. The 'ideal wind' score leaps to 33%, making April the first month of the year with a reliable offshore component. Water temperature cools to 24.2°C, air temperature averages 22.3°C, and rainfall drops to 1.70mm/day. This is the start of the autumn clean-up-expect more mornings with lined-up peaks, less chop, and increasingly powerful surf.
