How to Choose a Kitesurfing Wetsuit for Portugal

One of the most common questions we hear from visitors arriving to do their first kitesurfing lessons at Costa da Caparica is: what wetsuit do I need? The answer depends on what time of year you’re coming and how your body handles cold water.

Why Wetsuits Matter More in Kitesurfing Than You Might Think

Even on a warm summer day at Costa da Caparica, the Atlantic water along Portugal’s west coast runs significantly cooler than the air temperature. The combination of wind chill while you’re riding, repeated wipeouts, and long sessions means your body loses heat faster than you’d expect. A wetsuit isn’t just about comfort — it directly affects your performance and focus.

Portugal’s Water Temperatures Through the Year

In summer (June–September), surface water temperatures at Costa da Caparica typically sit around 17–20°C. In winter (December–March), water drops to around 14–16°C — cool enough that experienced riders reach for a wetsuit year-round.

The Thickness Guide for Costa da Caparica

For summer kitesurfing — roughly May through October — a 3/2mm full suit is the standard choice. In peak summer heat some riders are comfortable in a 2mm shorty. For autumn conditions, a 4/3mm suit becomes more appropriate. For winter — November through April — a 5/4/3mm or a 4/3mm with a thermal underlayer is generally comfortable for most riders.

Fit, Flexibility, and the Details That Make a Difference

A wetsuit that fits well and moves well is worth its price tag many times over. Check that there are no large air gaps at the neck, wrists, or ankles — those are where cold water flushes through and strips your warmth away. The suit should feel snug across the shoulders without restricting arm movement when you extend overhead.

Accessories for Cold-Water Sessions

When winter conditions push water temperatures below 15°C, most riders add neoprene gloves, booties, and a hood. The head loses heat disproportionately fast — on a January session with 20-knot winds, keeping your head covered extends your comfortable riding time considerably.

Caring For Your Wetsuit

Rinse your suit with fresh water after every session, turn it inside out to dry, and hang it on a wide hanger. Salt, UV light, and general wear are the enemies of neoprene — a well-maintained suit can last several seasons.
