Amado seasonal overview

Best Surf Season (October - March)

The North Atlantic is fully awake from October through March, delivering consistent, powerful swell to Amado's west-northwest facing beach. Average wave heights range from 1.8m in October to a peak of 2.4m in December, January, and February, with long-period groundswells averaging 11-13 seconds. The combination of deep low-pressure systems tracking across the Atlantic and a favorable NAO pattern funnels swell from the WSW through NW bands directly into the bay. Ideal offshore wind conditions (from ONO, O, OSO, SO) occur 22-29% of the time, often during post-frontal high-pressure setups with crisp, clear skies. This is prime time for pumping surf in the 1.5-2.5m range, with occasional XL days exceeding 2.5m for the charger crew.

Fair Surf Season (April - May & September)

As the winter storm track begins to retreat in spring, swells become less consistent but still offer quality sessions. April averages 1.9m with a period of 11.1s, while May drops to 1.6m and 9.8s. September sees a noticeable uptick as autumn gets underway, with averages of 1.5m and 10.4s. These months are characterized by a mix of fading winter groundswells and building summer windswells. Ideal wind windows narrow to 11-15% of the time, but when they align, the waves can be fun, rippable and clean. North to northwest windswell often dominates, but a solid W or WSW groundswell with light offshore winds can produce epic sessions.

Low Surf Season (June - August)

Summer is the quietest period at Amado. Average swell heights drop to just 1.4m and periods shorten to 8-9 seconds, indicative of weak, short-period windswell. The vast majority of the energy comes from the NW and NNW quadrants, often with onshore winds from the same directions, creating choppy, messy conditions. Ideal offshore wind conditions occur a mere 5-8% of the time, mostly during early morning land-breeze setups from the E/NE quadrant. While persistent small waves and light winds might appeal to beginners, experienced surfers will find the surf groveling at best. This is the season to explore other breaks or plan trips to the southern hemisphere.

Conditions at Amado in December

December: Prime Time Peak

December is the absolute peak of the surf season at Amado. Average swell height hits 2.4m with a 12.6s period – the largest and most powerful of the year. The swell comes predominantly from NW (23.7%), WNW (15.1%), and NNW (10.9%), with a notable increase in W (5.2%) and WSW (2.5%) energy. Wave heights in the 1.5-2.5m range account for over 50% of observations, and over 2.5m waves occur 3.3% of the time, offering genuine charging opportunities. Ideal wind conditions are at their annual maximum of 29%, thanks to frequent high-pressure systems that park to the north, drawing in cool, dry offshore winds from the ONO and O quadrants. This is the month when the North Atlantic aligns perfectly – expect pumping, firing surf day after day, with the potential for epic sessions that will be remembered for a lifetime.
