Choosing the right wetsuit according to water temperature
Surfing requires equipment that is adapted to weather conditions and water temperature. Wetsuits are essential for ensuring comfort, safety and freedom of movement during surf sessions. However, it can be difficult to choose the right thickness of wetsuit to suit the season and the geographical area. In this guide, we offer some advice on how to select the right wetsuit according to water temperature.
Different types of wetsuit
There are several types of wetsuit, each with its own advantages and disadvantages :
-
"Fullsuit" wetsuits : they cover the whole body, including the arms and legs, and are ideal for cold water and winter conditions.
-
"Shorty" wetsuits : with short sleeves and medium-length legs, they’re better suited to warmer waters and the spring and autumn seasons.
-
"Springsuit" wetsuits : similar to shortys but with long sleeves, they offer extra protection against the sun and chafing without sacrificing mobility.
-
Neoprene tops : worn on their own or under a wetsuit, neoprene tops provide an extra layer of thermal insulation for the torso and arm areas.
The main feature to consider when buying a wetsuit is its thickness, which is generally given in millimetres (mm). The thicker the neoprene, the more it retains body heat and protects against the elements. However, a wetsuit that is too thick can restrict mobility and impair board performance.
How do you choose the thickness of your wetsuit according to the temperature of the water ?
The thickness of a wetsuit should be chosen according to water temperature and weather conditions. Here's an overview of the different thicknesses recommended according to water temperature :
-
Water temperature above 24°C : A simple swim suit or Lycra top is usually all you need to protect yourself against the sun and skin irritation.
-
Between 20 - 24°C :Opt for a shorty or springsuit with a 2 mm thickness to guarantee good thermal insulation without sacrificing freedom of movement.
-
Between 16 - 20°C : A 3/2 mm full-body wetsuit (3 mm for the torso and 2 mm for the arms and legs) is recommended for comfort and protection against the cold.
-
Between 12 - 16°C : Choose a 4/3 mm full-body wetsuit for optimum insulation while retaining a degree of flexibility.
-
Between 8 - 12°C : A 5/4 mm full-body wetsuit with balaclava, gloves and neoprene boots is essential for braving the cold waters without risking hypothermia.
-
Below 8°C : Full-body wetsuits 6/5 mm or thicker, accompanied by suitable accessories (balaclava, gloves, boots), are essential when surfing in icy waters.
The variables to be considered
Although these recommendations are valid in most situations, it's important to remember that everyone reacts differently to the cold. Some surfers may need an extra layer to keep warm, while others may be happy with a thinner wetsuit. The length of sessions, personal sensitivity to cold, physical activity and weather conditions should also be taken into account when choosing the right wetsuit.
Other criteria for choosing your wetsuit
As well as water temperature and thickness, there are other factors to consider when buying a wetsuit :
-
The quality of neoprene : soft, elastic material for greater freedom of movement and added comfort.
-
The seams : suits with sealed seams (glued or taped) offer better insulation and greater durability.
-
The closing system : models with a zip at the back are generally easier to put on, while suits with no zip (zip-free) or with a front zip (chest-zip) provide better waterproofing and flexibility.
-
Accessories : balaclavas, gloves and neoprene boots help to improve thermal insulation and protect the body's extremities from cold and injury.
In short, choosing the right wetsuit depends on a number of factors, including water temperature, neoprene thickness, the quality of the materials and additional features. By taking these criteria into account and adapting your equipment to local conditions, you'll be able to enjoy your surf sessions to the full while staying warm and protected.
