May ramps toward summer: warmer water, long days, and fewer winter-hardy surfers—before the July rush. Swell can be patchier than autumn, but fun pulses still arrive with space in the water. Below: conditions, kit, crowds, and flat-day options around Aljezur.

Wave conditions
May sits in the shoulder: the North Atlantic is not firing like October–March, but you are not yet in the small summer pattern of June–August. Expect weeks where 0.5–1.5m-ish surf is common, with occasional bigger days if a system tracks favorably.
Wind: the Nortada (NW) builds toward summer but is usually weaker in May than in July. Morning sessions still win for glassier conditions. As the land heats, afternoon onshores can appear—plan land activities for then if the chart looks breezy.
Tips:
- Flexibility beats fixation on one spot; if your home break is tiny, scout Arrifana or other picks that pick up slightly more swell.
- Longboards and higher-volume shapes shine on weaker days—see what surfboard should I rent.
What to wear
Water ~17°C: early May, most people stay in a 4/3mm. By the last third of the month, locals and visitors often move to a 3/2mm, especially for shorter sessions or warm afternoons.
Boots are personal—some drop them late May; others keep them for reef or longer surfs. The wetsuit guide for Portugal maps thickness to season if you want a simple rule set.
Crowds and accommodation
May is pre-summer. Beaches have surfers and a few tourists, but you are not fighting August-style parking wars. Accommodation is easier to find than in July, and nightly rates are usually below peak—good for a week of surf-and-hike without paying high-season premiums.

Best activities beyond surfing
May is prime hiking weather on the Costa Vicentina: warm sun, long days, and trails that are not yet scorching midday. If the swell drops, the Rota Vicentina is an easy win.

One-week reality check in May
If you are booking seven days, assume you will get a mix: a couple of genuinely fun sessions, a few average ones, and maybe a flat stretch where hiking or a day trip makes more sense than forcing a surf. That is normal shoulder-season surfing—not a sign you picked the wrong coast. Bring a longboard mindset (or rent one) for weaker days, keep an eye on period and direction rather than only wave height, and remember that a slightly bigger tide stage can turn a closeout bank into something workable. Locals often surf shorter sessions in May because the water is still cool—quality over hours keeps you keen for the whole trip.
Why May might be right for you
Choose May if you want space in the lineup, mild air, warming water, and a lower accommodation bill than summer. Pass if you need guaranteed powerful swell every day—winter and autumn are more reliable for that.
