January: Summer Trades and the Glassy-Window Hunt
January is peak summer in southern Brazil, and the South Atlantic High is in full control. The wind rose shows a heavy NE (24.6%) and ENE (22.7%) presence, with another 10.7% from E; most of those directions clock in between 10-30kph and they are blowing onto or across the beach. Only 14% of the time does the wind go ideal (WSW/W/WNW/NW), so clean, lined-up conditions are a genuine commodity. The swell side is dominated by ENE (23.7%), E (22.4%) and ESE (16.8%), producing an average height of 5.2ft (1.6m) at a short-to-average 8.1s period. Most waves fall in the 3-6.5ft (1-2m) category, which means there is plenty of fun-sized, rippable water if you can find a window. With air temperatures near 24.0°C, water temp at 23.9°C and about 4.2mm/day of rain, the surface is warm but often lumpy; the smart play is to wait for a frontal system or local wind shift that brings W/NW flow and grooms the constant ENE/E swell.
