Conditions at Leblon in October
October: Spring Transition, Smaller Swell and Trickier Winds
October marks the start of Leblon's less consistent season. Average swell height drops to 1.3m (4-4.5ft) and period shortens to 10.0s. The direction remains mostly south: SSE 26.3%, S 22.5%, SE 21.2%, ESE 19.2%, but the height distribution cascades down - only about 26% of swells reach 1.5m (5ft), and most of the energy sits in the 1-1.5m class. The bigger issue is wind: ideal surfing wind bottoms out at 38%. E winds are the most common at 21.1%, ENE adds 17.2%, and SW/WSW onshore flow grows to 15.5%. Water temp is at the annual minimum around 20.6°C, air averages 22.7°C, rainfall 3.51 mm/day. Don't expect June-style perfection; look for early-morning offshore windows and pulsing SSW swell.
