Machico - surf spot statistics

Best Surf Season (October - March)

The North Atlantic roars to life during October through March, delivering the most substantial swell energy of the year to Machico. With average wave heights ranging from 2.0m to 2.6m and periods between 11.5 and 12.9 seconds, this is when the spot sees its most powerful, long-period groundswell. The dominant swell directions from the NW and NNW wrap nicely around the island, but the key ingredient is wind: when a strong Atlantic high-pressure system sets up, it can draw in offshore winds from the W, WNW, or NW, creating clean, lined-up surf. However, these windows are not constant – ideal wind conditions occur only 29% to 47% of the time during these months, so patience is required. When the synoptic puzzle aligns, the result is pumping, heavy waves that will light up any surfer's day. The chance of a full-on XXL episode is highest in this season, especially during January and December when average swell heights push past 2.5m.

Fair Surf Season (April - June & September)

As winter storms gradually weaken and the Azores High builds, April through June marks a transition to more consistent but smaller surf. Average wave heights drop to 1.5-2.1m, and periods shorten to 9.3-11.2s, reflecting a mix of weakening groundswell and increasing windswell. The wind patterns become more favorable for surfing, with ideal offshore flows occurring 51% to 64% of the time. The predominant wind direction shifts to N and NNE, which are side-offshore for Machico, often creating glassy or lightly textured conditions. The waves are still solid and rippable, especially during April and May with average heights around 1.7-2.1m. September also falls into this category, as the first autumn swell pulses begin to arrive while late summer winds remain favorable (58% ideal wind). Fair season offers reliable fun-sized surf with far fewer blowouts than full winter.

Low Surf Season (July - August)

July and August represent the quietest months for surf at Machico in terms of wave height and power. Average swell heights dip to 1.4m with periods under 9.1s, driven primarily by weak, short-period windswell from the N and NNE quadrants. While the percentage of favorable offshore wind is still high (56-58%), the waves are often too small to generate any real drive. The trade wind regime dominates, with winds blowing consistently from the N and NNE, keeping the sea surface fairly clean but offering little in the way of rideable face. This is the time for micro-session groveling or a backup plan if your expectations lean toward shoulder-high surf. The plus side is the consistency of clean conditions for other water activities and the occasional fun-sized day when a rare south-east quadrant swell sneaks in – but those remain very uncommon. For serious wave-chasers, this is the off-season.

May: Clean Fun in the Sun

May sees the surf settle into a classic spring pattern. The average wave height drops to 1.7m and the period shortens to 10.0 seconds, reflecting a mix of weakening groundswell and increased windswell from the north. The dominating swell direction is NNW (34.2%) and NNE (15.9%), with notable contributions from N (12.4%) and NW (16.9%). The waves are still punchy enough for shortboards, especially at 1-1.5m or 1.5-2m heights. The wind conditions are even better: ideal offshore flow now 56% of the time. The wind rose shows strong NNE (26.4%) and N (24.2%) components, which blow side-offshore, producing clean, organized lines. Occasional light variable winds in the afternoon add to the appeal. The surf is far less consistent in size than winter, but the quality-to-quantity ratio is high. Expect plenty of head-high peaks with a cruiser vibe – perfect for logging longer sessions.
