Conditions at Rockaway-Manzanita in March
March: Late-Winter Power with Spring Wind
March keeps the swell alive with average heights around 8-9ft (2.4-2.6m) and a solid 11.9s period. The swell window tightens and strengthens: W accounts for 19% and WNW for 18%, with WSW adding 11%. Most waves fall in the 5-8ft (1.5-2.5m) range, and occasional larger sets keep the focus on the bigger break. There is still plenty of late-season power in the water.
The spring transition begins to weaken the offshore flow. Ideal E, ESE and SE wind drops to 26%, while NNW, S and SSW winds combine for a lot of cross-shore to onshore texture. Rain eases a bit to 6.31mm/day, air temps average 6.7°C, and water temperature is a cool 9.8°C. Look for post-frontal easterly gaps to score clean, powerful waves before the afternoon sea breeze takes over.
