Conditions at Rosa in April
April: The Real Season Starts to Build
April is where Rosa begins to shine. The average swell height rises to 4-5ft (1.3m), the average period reaches 9.0s, and the direction spread becomes beautifully balanced: ESE (21%), SE (20%), E (19%), SSE (16%) and S (9%). That southern component is critical, as it feeds more organized, longer-period energy into the ESE-facing beach. A solid 10-15% of the swell is in the 1.5-2m (5-6ft) range, with a smaller but noticeable share from S reaching 2-2.5m (6-8ft).
Offshore wind windows open up too, with ideal conditions 40% of the time. NNE (21%) and NE (14%) are still the most frequent directions, but SSW (10%) and SW (8%) are becoming regular players, and WSW/W/NW winds are more common than in summer. Water temperature drops to 23.3°C, air averages 20.9°C, and precipitation is down to 3.31 mm/day. This is a quality month to be in the water.
