Larido seasonal overview
Best Surf Season (December - February)
The core of winter sees the North Atlantic at its most active, with powerful extratropical cyclones marching across the basin. Larido, with its west-southwest exposure, captures the brunt of these long-period swells. Average wave heights hover around 1.7-1.8m with periods frequently reaching 12-13s, delivering pumping, heavy surf in the 1.5-2.5m range. Offshore winds from the NNE through E quadrant blow over 40% of the time, keeping conditions clean. This is prime time for serious waves, especially when a high-pressure ridge builds behind a front, bringing sunny skies and glassy conditions.
Fair Surf Season (March - May & September - November)
During these shoulder months, energy levels are more variable. Spring sees a gradual decline in swell size and period as the jet stream retreats, with March still offering solid 1.5m waves but May dropping to a fun 1.0m average. Autumn sees a reverse ramp-up: September provides small but punchy groundswells from early-season storms, while October and November see size and period increasing sharply. Winds remain favourable around 37-40% of the time, though southerly onshore flows become more common. Expect rippable, fun-sized waves on the better days, with occasional pumping sessions when a storm aligns with offshore winds.
Low Surf Season (June - August)
Summer is the quietest period for Larido. The Atlantic storm track shifts north, leaving the region dominated by weak, short-period windswells from the northwest. Average heights bottom out at 0.8-0.9m with periods around 7s, resulting in small, often choppy conditions. While offshore breezes from the northeast persist roughly 36-39% of the time, the lack of swell energy means most days are for groveling on small boards. Only occasional pulses from distant southern hemisphere storms or localized summer seabreezes can produce a brief window of fun waves, but overall this is a time for smaller craft and patience.

Conditions at Larido in September
September: Autumn Stirrings
September marks a clear transition with average swell height edging up to 1.0m and period to 8.8s. Swell direction shifts back to a strong W-WNW influence: WNW (32.5%), W (14.9%), and NW (23.7%). The proportion of 1-1.5m waves increases, and there are more 1.5-2m sets (3% from WNW). Offshore wind frequency is 40%, with NE (16%) and NNE (17.3%) still dominant, but southerly winds (S 8%, SSW 8%) become less frequent. This month often sees the first punchy, rideable swells from early-season lows. Despite the modest average, the period is long enough (8.8s) to produce fun waves when combined with a north wind. Watch for the first big groundswell of the season by late September.
