Conditions at Rincao in October
October: Spring Transition Brings Size but Turbulence
October marks the start of the spring transition. Average wave height remains solid at 5ft (1.6m), but the period drops to 8.9 seconds. Swell is heavily influenced by E and ESE directions, together accounting for over 41 percent of the wave energy, with ENE at 16 percent as well. The faster, more wind-driven swell mixes with longer-period southern background, so the surf is often a blend of grovelling trade-swell and punchy groundswell.
The wind odds weaken to only 21 percent ideal, the lowest of the year. NE and ENE winds are strong, blowing over 40 percent of the time, and the E/ESE/SE/SSE onshore components increase, making surfaces lumpy. Water temperatures warm to 18.8°C and air temps to 19.4°C with 4.33mm/day rain. October can be rewarding when a front pushes east and turns the wind W/NW, but patience is required.
