Playa Junquillal seasonal overview

Best Surf Season (November - April, July)

Playa Junquillal experiences a distinct split in surf quality driven by the seasonal migration of the Intertropical Convergence Zone (ITCZ) and the strength of the North East Trade Winds. The best surf conditions unfold from November through April when the trade winds are at their peak, supplying consistent offshore winds from the NE and ENE. During these months, the average wave height hovers around 1.3m with periods ranging from 11.5s to 14s, offering punchy, long-period swell. Although swell direction is more mixed, the dominant SSW and SW swells still hit the beach at an optimal angle, and the high frequency of offshore winds ensures glassy, clean faces. July also stands out as a prime month, as the trade winds relax and offshore flow becomes exceptionally frequent (79% ideal), while the swell remains almost exclusively from the SSW and SW at 1.5m and 13.5s periods – a recipe for powerful, well‑shaped waves.

Fair Surf Season (May, June, August)

These months see the transition between the dry and wet seasons, bringing more variable conditions. The ITCZ shifts northward, weakening the trade wind regime and causing a higher incidence of onshore winds, particularly from the SW and WSW. Swell heights remain solid (1.4–1.5m) and periods are long (13–14s), with nearly all swell arriving from the optimal SSW/SW window. However, the lower percentages of ideal wind (58–67%) mean that while the ocean delivers plenty of power, the surface texture isn’t always clean. Expect plenty of fun, rippable waves, but with a greater chance of bumpy or wind-affected conditions compared to the top months.

Low Surf Season (September, October)

The heart of the wet season brings the poorest surf window to Playa Junquillal. The ITCZ is overhead, leading to frequent onshore wind flows from the SW and SSW. The average swell heights remain at 1.5m and periods are still long (13s), but the ideal wind percentage drops to 49–55%. This means the wave quality is often compromised by strong onshore winds, creating choppy and messy conditions. Additionally, the increase in tropical instability and potential for storms can bring occasional windows of good swell, but they are often accompanied by unfavorable winds. These months are best for patient surfers willing to wait for the right combination of a passing cold front or tropical wave that aligns with a rare offshore breeze.

Conditions at Playa Junquillal in August

August: Slight Dip, Still Good

August sees a minor decline in ideal wind (67%) as the trade winds weaken further. Swell is still dominated by the SSW (77.3%) and SW (14.8%) with a steady 1.5m average height and 13.3s period. The 1.5–2m category holds strong (28.4% from SSW). Wind directions are more varied, with NE and ENE making up only 28.5% of the total, while onshore flows from the S and SW increase. However, the high swell consistency means that even on average days, waves are rideable. The best windows come with stronger offshore pulses, often ahead of light morning land breezes.
