El Porto seasonal overview
Best Surf Season (November - February)
El Porto is at its prime when the North Pacific storm track is firing. From November through February, the average swell period holds at 12-12.5s and the swell rose is locked into the W, WSW, and SW quadrants that face this west-southwest-facing beach. Offshore wind probabilities peak at 46-51%, especially in December and January, which means clean morning windows with light NE/ENE/E/ESE flow are common. This is the season when long-period W and WNW groundswell can wrap into the sandbars and deliver clean, punchy 3-5ft (0.9-1.5m) waves, with occasional 5-8ft (1.5-2.5m) sets when a strong Gulf of Alaska low lines up with Southern California. The weather is cooler and wetter, but the abundant swell and better winds make this the most reliable time of year at El Porto.
Fair Surf Season (March - May and September - October)
The shoulder seasons offer real potential with a few more caveats. March and April still see solid W/WSW groundswell, but ideal offshore wind drops to 35-38% as the daily sea breeze strengthens. May marks the shift toward summer, with southern-hemisphere SSW/SW energy beginning to mix in and clean-wind percentages falling further. September and October are the fall mirror: water temperature is at its warmest, tropical-driven long-period SW/SSW swell can show up, and offshore wind odds improve from 30% in September to 39% in October. These months are less consistent than winter, but when a long-period west swell aligns with a light offshore wind, El Porto can still serve up steep, rippable peaks.
Low Surf Season (June - August)
Summer is the slow season at El Porto. The North Pacific High settles over the region, average swell heights hover around 2-3ft (0.6-0.9m), and the dominant SW/WSW swell trains are long-period but often undersized. The main problem is wind: thermally driven SW/W onshores build almost every afternoon, and ideal offshore conditions occur only 24-30% of the time. The low season still has its moments, mainly at dawn before the sea breeze arrives or when a southern-hemisphere groundswell lights up the SW window. Those windows are smaller and less powerful, but they keep the sandbars moving through the summer.
