Do You Need a Wetsuit for Kitesurfing in Summer? — Explained

The short answer: no, you don't need a full wetsuit for summer kitesurfing in warm water. Most of Europe's summer conditions (Mediterranean, Atlantic coast, and Baltic warmth patches) allow you to ride in board shorts and a rash guard. However, protection from the sun and minor scraped is non-negotiable--even in the hottest months.

The Full Answer

Whether you need a wetsuit for summer kitesurfing depends entirely on water temperature, air temperature, and how long you plan to be in the water. In Southern Europe--Greece, Croatia, Portugal, southern France, and Spain--summer water temperatures regularly reach 22-26°C. At those temperatures, a thin 2mm shorty or a rash guard alone is comfortable and safe. Many experienced riders simply wear board shorts and go bare-chested, but that's where UV damage becomes your biggest risk.

Northern Europe tells a different story. The Baltic and North Sea, even in July and August, stay in the 16-20°C range. A 3/2mm spring suit or 2mm shorty becomes practical, not luxury. That said, if you're riding in 20°C water for an hour, you'll stay warm enough without full coverage--but your skin won't thank you for the sun exposure.

The real issue isn't warmth; it's sun protection and abrasion resistance. A rash guard serves both purposes: it blocks UV rays (which are strongest at midday on the water) and protects your back, shoulders, and torso from the board, boom, and kite lines during crashes. Most summer riders we see at Surf Store wear at least a lycra or neoprene rash guard, even if they skip the full suit.

One more consideration: water quality and sea life. Summer algae blooms and jellyfish are more common in warm months. A thin wetsuit acts as a barrier. Plus, if you're riding regularly (3-4 sessions per week), a suit speeds recovery and reduces chafe from constant friction.

Practical Guide

• ◈
  Check water temperature -- Use local marine forecasts or buoy data. Below 18°C, a 3/2mm suit is practical; above 22°C, a rash guard alone usually suffices.
• ◈
  Invest in a quality rash guard -- Brands like ION and Mystic make lightweight UPF-rated guards that dry fast and protect your torso from sun and scrapes. Essential year-round.
• ◈
  Ride early or late -- Peak UV is 11am-3pm. Morning and late-afternoon sessions mean less sun exposure and often better wind anyway.
• ◈
  Bring sunscreen and reapply -- Even with a rash guard, exposed skin (face, neck, forearms, calves) needs SPF 30+ every 2 hours.
• ◈
  Consider a thin spring suit for frequent riders -- If you're on the water 4+ days per week, a 2-2.5mm shorty balances comfort, protection, and durability without overheating.
• ◈
  Test your comfort level in shallow water first -- Spend 20 minutes in knee-deep water to confirm you're not going to shiver or overheat before committing to a full session.

Common Mistakes

Surf Store Recommendation

For summer kitesurfing in warm water, we recommend a lightweight rash guard as your first purchase--even before a thin wetsuit. Brands like ION and Mystic make excellent UPF-rated lycra and neoprene rash guards that are breathable, quick-drying, and offer real sun and abrasion protection. Most riders pair a rash guard with board shorts for water above 20°C.

If you're in cooler summer waters (Baltic, North Sea, Irish coast), a 2-2.5mm shorty from NeilPryde or Mystic gives you the warmth of a full suit without the bulk. These are thin enough to stay cool but offer proper thermal protection for sessions longer than an hour. We stock both options in every size at Surf Store--come try them on before you buy.
