Conditions at Impossibles in March
March: Transition Begins
March marks the first real taste of dry-season weather. Ideal wind jumps to 48%, and while W and WNW flow is still present (combined 27.8%), the rise of E to SE trade winds-now over 30% combined-adds welcome variety. Swell averages 5.2ft (1.6m) but the period lengthens to 13.3s, hinting at deeper low-pressure systems in the Southern Ocean. The SSW direction has strengthened to 58.8% of the energy, with SW adding 30.8%. There is a greater share of 3-5ft (1-1.5m) surf (around 41%) than in the previous months, but still more than half the waves are 5-8ft (1.5-2.5m). Rain drops to 5.83mm/day, water remains warm at 29.3°C and air temperatures peak near 27.9°C. This month offers a genuine taste of Impossibles' potential as the winds begin to align.
