Conditions at Playa Nosara in October
October: Maximum Size, Variable Winds
October keeps the tropical-surf momentum going. The average swell height remains 1.5m, the period is still a strong 12.9 seconds, and the SSW/SW sectors make up 95% of all swell energy. The SW component grows to 35.9%, and a significant 15.7% of the total swell sits in the 1.5-2m range, with another 1.5% over 2.5m. If you want raw size, this is the month - late-season tropical storms and strong South Pacific swells can deliver serious 6-8ft (1.8-2.4m) surf.
Winds are a mixed bag. Ideal conditions occur 44% of the time, with a higher frequency of onshore W and SW flow around 7% each, accompanied by 20-30kph gusts in some events. The good news is that when a high-pressure ridge sneaks in behind a tropical wave, the offshore NE trades reappear and groom these powerful swells into clean, hollow lines. It is a high-variance, high-reward month for the dedicated surfer.
Rainfall reaches the annual peak at 8.87mm/day and the water begins to cool to 28.1°C. October is a month for those willing to sit in the rain and dodge the odd storm swell - those who do are often rewarded with the biggest paddle sessions of the year.
