Conditions at Leblon in January
January: High Summer, Small Swell, Clean Windows
January sits deep in the Southern Hemisphere summer, with Leblon's average swell locked at 1.1m (3.5ft) and an average period of 9.5s. That period places the waves in the 'rideable but not overly powerful' range - punchy sections but little heavy groundswell. The swell direction is spread across ESE (21.1%), SE (20.3%), SSE (24.5%) and S (22.8%), so there is usually a mix of windswell and short-period south pulses. Only about 12% of the month reaches 1.5m (5ft) or bigger. Winds are favorable for grooming: N/NNE/NW/NNW offshore flow is present in light windows, and the ideal surfing wind percentage is 52%. The most common winds are ENE (17.2%) and E (15.0%), which are cross-shore and keep the beach a little textured through the afternoon. Water temperatures are a summer-warm 22.8°C, air temps average 25.6°C, and rainfall is high at 6.75 mm/day - so chase the dawn patrol for clean small waves.
