During this period, ground swell dominates (63-91% of the time), providing powerful, clean waves with an average swell size ranging from 1.7m to 2.2m. The winter months, especially December, January, and February, offer the largest and most reliable swells (2.2m mean size) and the highest percentage of ground swell (84-91%). Wind conditions are less favorable in these months, with bad winds occurring 63-66% of the time, but offshore winds still manage to appear 34-37% of the time, creating excellent surfing windows. Spring (April-June) and summer (July-September) see a decline in quality, with wind swell becoming more prevalent (35-83%) and swell size dropping to 1.1-1.7m. Summers are particularly challenging, with weak swells (1.1-1.3m) and frequent onshore winds (bad conditions 73-82% of the time). September marks the transition back to better surf, with ground swell increasing to 46% and the first signs of improved wind conditions (27% good winds). October and November are strong rebound months, bringing back solid ground swell (63-74%) and improving winds (33-34% favorable), making them excellent choices for surfers looking for a balance between wave quality and fewer crowds. Overall, the best window for high-performance surfing in Ericeira is from October to March, with the peak consistency and power found in the winter months despite the wind variability.

October in Ericeira delivers solid surf conditions with an average swell height of 1.7m and a strong period of 11.3s, producing well-organized, powerful waves. The dominant swells come from WNW and NW directions, with the highest frequency in the 1-2.5m range, ensuring consistent, quality setups. Around 33% of the time, winds are favorable for surfing—typically light to moderate offshore or cross-shore from the north and northeast. However, stronger onshore winds from the south and southwest can occasionally disrupt conditions, particularly when speeds exceed 20kph. Expect a mix of manageable mid-sized days and occasional larger, more powerful swells, making it a reliable month for intermediate to advanced surfers. The spot’s exposure to Atlantic energy ensures plenty of rideable days, but wind management remains key for optimal sessions.
