Inatel seasonal overview
Best Surf Season (October - March)
The North Atlantic is the engine that drives Inatel, and it is at full power from October through March. With the south-facing beach needing swell from the south, south-southwest, and southwest to really light up, winter is the clear winner: the storm track dips toward Iberia more often, average surf heights climb to 3ft (0.9-1.0m), and average periods sit in the 10-12s range. That long-period energy is exactly what puts punch in the water. The same frontal systems that drag S/SW swell across the Atlantic also leave behind cooler north to northeast winds, so offshore conditions blow 24-35% of the time through this window. On top of the usual storm track, the North Atlantic Oscillation is key: when it is negative or neutral, low pressures tend to dive farther south, opening the S/SW window more often for Inatel. This is prime time.
Fair Surf Season (April - May and September)
April and May are transitional months. The Azores High starts to build and the storm track lifts north, so size drops to 2-3ft (0.6-0.9m) and average periods slide from 9.1s down to 7.8s. The swell becomes more windswell-dominated and less consistent, especially for a south-facing spot. September is the mirror image: the Atlantic wakes up again, periods climb back toward 8.6s, and the first real S/SW pulses appear. These months are not the core season, but they can reward surfers who are patient and choose their windows.
Low Surf Season (June - August)
Summer is the quietest chapter at Inatel. The Azores High locks in over the eastern Atlantic, the North Atlantic storm track pushes toward Iceland, and the surf is left with small, short-period northwesterly windswell. Average heights bottom out at 1-2ft (0.5m) and average periods drop to only 6-7s, while true offshore wind blows just 10-14% of the time. There will be the odd south-swell pulse or clean morning, but on average June through August is the time to book a trip elsewhere or bring a longboard.
