Conditions at Isla Uvita in March
March: Still Good, But the Engine Is Backing Off
March keeps the trade-swell conveyor belt moving, but with a little less steam. ENE swell still dominates with 83%, NE adds 13%, and the average height steps down to 3.9ft (1.2m). Periods drop to 8.1s, and the distribution shifts away from the bigger 1.5-2m peaks toward the 3-5ft (1-1.5m) fun zone. Expect punchy, waist- to chest-high waves that are still well worth paddling out for, especially on the better sandbars.
Wind quality is where March loses ground: ideal wind drops to 34% as the pressure gradient weakens and the easterly trades become more onshore. Rain is still low at 2.47 mm/day, air temps warm to 24.0°C, and water temps nudge up to 27.9°C. This is a transition month - the winter swell train is still running, but you have to be more selective and check the wind before you commit.
