La Rinconada - surf spot statistics

La Rinconada in Chile is a consistent surf spot with reliable ground swell throughout the year, rarely experiencing flat conditions (0% no swell). The swell is predominantly ground swell, averaging 90% or higher, ensuring quality waves with mean sizes ranging from 1.6m to 2.0m. The best months for surfers are from May to August, when swell size peaks at 1.9m–2.0m, offering powerful and clean waves. Wind conditions, however, are challenging, with bad winds (onshore or cross-shore) dominating 65%–78% of the time year-round. The least unfavorable winds occur from March to June, with good wind probabilities around 32%–36%, slightly improving wave quality during these months. While winter (June–August) brings the largest swells, spring (September–November) and fall (March–May) offer a balance between decent swell size and marginally better wind conditions compared to summer. Overall, advanced surfers will find the most consistent waves from late fall to early winter (May–July), despite persistent wind challenges, while those prioritizing cleaner conditions may prefer March–April when wind probabilities are slightly less harsh.

In September, La Rinconada offers solid surfing conditions with an average swell height of 1.7m and a healthy 12.9s period, indicating well-formed, powerful waves. The dominant swell directions are WSW and SW, contributing the most to rideable waves (1-2.5m range), while W and WNW swells occasionally bring larger sets (over 2.5m). Wind conditions are favorable for surfing 31% of the time, though southerly winds (S, SSE, SSW) frequently bring stronger gusts (10-30+ kph), potentially creating onshore chop. Offshore winds (NE to E) are rare but provide clean faces when they occur. For experienced surfers, September delivers consistent, mid-sized waves with decent power, but wind variability requires timing sessions carefully—early mornings or wind-protected spots may work best when southerlies dominate. Overall, a reliable month with a mix of quality swells and manageable wind disruptions.
