Conditions at Horseshoe in April
April: Waning Swell, Shifting Winds
April is a transition month. The northeast monsoon has loosened its grip, and the average swell height drops to 3-4ft (1.1m), with periods still a fair 9.4s. The swell mix is dominated by ENE at 66.3% and NE at 27.1%, but now the heights are much smaller: roughly two-thirds of the surf falls in the 2-5ft (0.5-1.5m) range. For Horseshoe, this is clean, friendly, rippable surf on the best days, though not the powerful overhead walls of midwinter.
Wind patterns are also changing. The dominant directions remain E/ENE/ESE - 25.3%, 21.7% and 17.0% respectively - but the speeds are lighter and the percentage of westerly offshore flow increases. The ideal wind index climbs to 5%, still low, but enough to make morning sessions worthwhile before the onshore sea breeze kicks in. The dry season is settling in, with rainfall down to 5.8mm/day, air temperature 27.8°C, and water temperature warming to 28.6°C. If you're chasing clean conditions rather than max size, April is a sleeper month.
