Praia da Macumba - surf spot statistics

Best Surf Season (May - August)

The South Atlantic winter unleashes its fury during these months, and Praia da Macumba stands tall to receive the onslaught. Average swell heights climb to a consistent 1.2-1.3m with periods stretching into the 10.8-11.1s range - that's punchy, long-period groundswell from the S, SSE and SSW quadrants. The percentage of offshore wind (N, NNE, NW, NNW) peaks at 51-57%, meaning cleaner, more groomed faces more often. This is when the combination of solid swell and favorable wind aligns to produce the best waves of the year.

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

Shoulder months bring a mixed bag. In March and April, the average swell height is around 1.0-1.2m and periods are still strong (10.4-10.6s), but offshore wind drops to 45-46%. September and October see swell heights remain decent (1.1-1.3m) but ideal wind falls to just 37-41% as the trade winds strengthen and blow more from the ENE-E, creating cross-to-onshore conditions. You'll still find fun, rippable waves, but you'll have to work harder to pick the right wind window.

Low Surf Season (November - February)

Summer in the southern hemisphere brings a lull in South Atlantic storm activity. Average swell heights hover around 0.9-1.0m with periods of 9.6-9.9s - mostly small, groveling waves from the SE and SSE. Offshore wind frequencies are moderate (37-51%) but the lack of size and power means the surf is often marginal. While occasional pulses of longer-period swell can ride through, expect mostly whitewash and weak conditions during these months.

August: Still Firing as Winter Fades

August is the tail end of the best season, but it still packs a wallop. Average swell height is 1.2m with 10.8s period, and the swell is evenly split between S (31.8%) and SSE (25.2%). There's a notable increase in ESE (13.1%) and SE (18.6%) swells, which may not be as well-refracted for the beach. Offshore wind stands at 51%, with NNE (12.9%) and NE (11.4%) leading. The quality remains high, but the transition to spring is starting - expect occasional southerly winds (SSW 4.7%) that can ruin a session. Overall, August still offers solid, firing waves for the dedicated surfer.
