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.

June: Peak of Summer Consistency

June delivers the highest percentage of ideal wind of any month, hitting 64% – a surfer's dream for clean conditions. The average swell height drops further to 1.5m and the period to 9.3 seconds, indicative of a windswell-dominated regime. The swell direction is heavily concentrated in the NNW (38.3%) and NNE (20.4%), with N (16.9%) and NW (14.6%) also contributing. These north quadrant swells wrap around the island, offering rideable waves in the 1-1.5m and 1.5-2m ranges. The persistent N and NNE winds (N 32.1%, NNE 33.9%) blow side-offshore, grooming the waves into clean, fun-sized lines. While the power of winter is absent, the consistency and quality of the surf are hard to beat. The lower period (9.3s) means the waves are punchy and forgiving. June is the go-to month for those seeking reliable, offshore surf without the heavy crowds of prime winter.
