Conditions at Praia dos Molhes in March
March: Autumn's First Signs of Power
March is the first real transition month. Average wave height bumps to 4.9ft (1.5m) and wave period lengthens to 8.8s, adding more push to the sandbars. Swell is still predominantly from E (20.7%), ESE (22.3%), and SE (18.5%), but the southern components SSE (15.3%) and S (8.6%) continue to grow. Ideal wind frequency reaches 34%, and the first strong cold fronts of autumn begin to drag westerly wind shifts over southern Brazil. However, NE and NNE winds still combine for about 28% of the time, so quality remains inconsistent. The best sessions will occur during and immediately after frontal passages, when the wind goes offshore from the west and the E/SE groundswell has enough period to stand up on the sandbars. Water temp is 23.7°C, air temps average 21.7°C, and the vibe is charged with the onset of the proper surf season.
