Conditions at Leblon in March
March: Autumn Transition into Longer-Period Groundswell
March is the first sign of Leblon's surf season turning up a notch. Average swell height edges up to 1.2m (4ft) and the period extends to 10.4s, giving the waves noticeably more push. The direction matrix becomes more south-oriented: SE 27.1%, SSE 32.6%, S 25.7%, while ESE drops to 10.6%. Around 20% of the swell now reaches 1.5m (5ft) or bigger, with S and SSE supplying most of the 1.5-2m and 2-2.5m sets. Ideal wind is 48%, and the wind regime is still summer-dominated - ENE (14.9%) and E (15.4%) - but the increasingly long S/SSE swell is enough to command the beach. Water temps warm up to 23.5°C, air averages 25.3°C, and rainfall is 5.76 mm/day. March rewards the surfer who can pick the south-facing windows as autumn takes hold.
