Conditions at Louro in April
April: Transitional Swells and Cleaner Westerlies
April marks the transition from winter grind to spring lull. Average swell drops to 4ft (1.3m) and the average period slides to 9.5s, meaning the energy is less intimidating but still rideable. WNW (27.9%) and W (19.1%) continue to supply the background pulse, while the ideal S-SSW-SW-WSW window sits at 13.2%. Offshore northerly winds blow 39% of the time, with NE (16%) and NNE (14.4%) the most reliable producers of clean, glassy conditions. Onshore S/SSW/SW/WSW winds are less dominant than in winter, creating more frequent clean windows, but the smaller size means a longboard may be the best friend. Water temperature rises slightly to 14.0°C, air temps average 12.7°C, and precipitation drops to 3.62 mm/day.
