El Chinchorro - surf spot statistics

Best Surf Season (November - February)

Winter at El Chinchorro is prime time. The North Atlantic winter pattern strengthens the trade winds and sends consistent east-northeast swell marching toward the Dominican south coast. Combined with a high frequency of offshore winds from the north and northwest (peaking at 76% in December), the surf becomes clean and punchy. Average wave heights range from 1.0 to 1.2m with periods around 6.2-6.5s, providing fun-sized, rippable waves. While the swell direction is not optimal (dominant from E to ESE), the offshore wind cleans up the faces nicely. This is the most reliable window for good waves.

Fair Surf Season (March - April & September - October)

During the spring and fall shoulders, the offshore wind frequency drops to the 53-56% range and the swell mix shifts more toward shorter period ESE swells. Wave heights thin to 0.8-1.0m, and the quality becomes more inconsistent. Still, there are plenty of groveling sessions to be had, especially when the wind swings clean.

Low Surf Season (May - August)

The summer months are the toughest for finding clean waves at El Chinchorro. Offshore wind percentages dip to their annual lows (as low as 47% in June), and the swell is almost exclusively from the ESE with short periods (6.2-6.6s). Wave heights hold around 1.0-1.1m but lack power and shape. The onshore winds from the south and southwest during this time can quickly turn conditions choppy. However, the Atlantic hurricane season can throw in some long-period gems if you keep an eye on tropical disturbances.

August: Summer Consistency with Lower Power

August holds onto the summer pattern with 61% offshore wind frequency, but the swell energy starts to wane. Average wave heights drop to 1.0m with a shorter period of 6.2s, making for smaller, less powerful waves. The dominant swell remains from the ESE and east, but the north winds (N 24.5%, NNW 18.1%) still clean things up nicely. It's a good month for logging or riding a small board – just don't expect overhead perfection. The hurricane season can inject some longer-period pulses, offering brief windows of excellent surf.
