Leblon - surf spot statistics

Best Surf Season (May - August)

The austral winter fires up the South Atlantic, and Leblon reaps the rewards. As deep lows track north of the Antarctic pack ice, they send consistent, long-period S and SSE groundswells marching toward Rio. May sees the swell engine really start to hum, with average heights climbing to 1.5m and periods stretching past 11 seconds. June and July are the peak months, offering the highest percentage of offshore winds from the north (N, NW, NNW) – over 57% of the time the breeze is clean. This is prime time: expect punchy, well-shaped waves in the 1-2m range, with the occasional pumping 2m+ set on the best days. The combo of solid swell and favorable wind creates firing conditions along this south-facing beach.

Fair Surf Season (March - April & September - October)

These transitional months bring a mix of quality and compromise. March and April still see decent S swell from late-season storms, with average heights around 1.2-1.4m and periods in the 10-11 second range. However, the wind is more variable. Frontal systems passing south of Brazil can swing the breeze onshore from the S or SE, dropping the ideal wind percentage to around 48%. When a high-pressure system settles over the continent, expect light offshore northerlies and clean, fun waves. September and October see a similar pattern – the beginning of the spring transition. Swell remains solid in September (1.5m avg) but onshore winds become more frequent as the ITCZ shifts. October is the toughest month, with only 38% offshore wind. Patience and a keen eye on the forecast are key during these months.

Low Surf Season (November - February)

Summer settles in over Rio, and the surf takes a mellow turn. The South Atlantic storm track weakens and shifts poleward, resulting in smaller, shorter-period swell. Average heights drop to 1.1-1.3m and periods hover around 9.5-10 seconds. While there are still pulses of S swell from occasional cold fronts, they are less frequent and smaller. On the bright side, summer also brings a higher chance of light offshore winds, especially in December and January when the wind blows from the north up to 52% of the time. The waves become fun-sized and rippable, perfect for logging or groveling on a shortboard, but don't expect any pumping, firing days. It's a great time for beginners or for those looking to work on their technique in smaller, cleaner conditions.

February: Small but Consistent

February mirrors January in many ways, with the average swell height stuck at 1.1m and a slightly longer period of 9.8s. The swell distribution is nearly identical, with SSE and S directions combining for nearly 47% of the energy. There's a slight uptick in 1-1.5m waves from the SSE and S, which can produce clean, rippable lines when the wind behaves. And behave it does – February boasts a 55% ideal wind score, one of the best of the year. Light NNE and NE winds dominate, with a good portion of offshore ENE flow as well. This month is all about quality over quantity. If you find a pulse of new S swell, you can score fun, punchy waves in the waist-to-chest high range with clean faces. It's a solid month for intermediate surfers looking to improve.
