Conditions at Playa Ostional in March

March: The Southern Hemi Shift Begins

March signals the beginning of the real transition. The swell direction becomes dramatically more favourable: SSW accounts for 39.0% and SW for 24.5%, giving Playa Ostional a 71.5% share of optimal SSW-W swell. The average period climbs to 13.2s, so the ocean is stacking up with more powerful, longer-period lines while average size remains a very rippable 4ft (1.3m). The NE trades are still solid but lighter than mid-winter, with NE at 38.1%; ideal wind sits at 39%. Air temp averages 29.0°C, rain stays minimal at 0.14mm/day and water temperature warms to 28.6°C. March is the strongest of the dry-season months and a good bridge into the groundswell season for surfers who want long-period swell without huge, disorganised power.
