Conditions at Puerto Madero in March
March: The South Swell Engine Starts to Turn
March brings a clear shift: average swell height nudges up to about 4ft (1.2m), the period jumps to 13.4s, and the SSW direction dominates a full 51.5% of the spectrum, with SW adding 30.1%. This is the first month where the wave trains start to look like true South Pacific groundswell, and there are now meaningful pockets of 5-6.5ft (1.5-2m) surf, especially from SSW and SW. On the wind side, ideal offshore conditions are only around 43% - the lowest of the year - as WSW and W flow combine close to 23% of the time. Still, the longer, more powerful swell can overcome some surface texture, especially on mornings with N/NW flow. Air temperatures reach 28°C with a range of 24.2-31.9°C, water temperature warms to 29.1°C, and rainfall is still light at 0.88 mm/day, setting the stage for stronger spring swells.
