How to Choose a Wetsuit, Thickness, Temperature Ratings

When choosing a wetsuit, there are a few factors to consider. The thickness of the wetsuit is essential, as thicker suits offer more insulation against the cold water. The temperature ratings of the suit are also essential to consider, as higher temperatures require thicker suits. Additionally, it is essential to consider whether you will swim or dive in your suit, as the type of activity will determine the appropriate thickness and temperature ratings.

There are a few things to consider when choosing the perfect wetsuit: thickness, temperature ratings, and style. 

Thickness is perhaps the most crucial factor to consider. A thicker suit will keep you warmer than a thinner suit, but it will also be heavier and more difficult to swim in. For cold-water diving and skiing, a suit with a thickness of at least 1.5mm is ideal. For warm-water diving and snorkeling, a suit with a thickness of only 0.8mm is preferable because it’s less bulky and offers more mobility. 

Temperature ratings are also essential to keep in mind when selecting your wetsuit. The higher the temperature rating of your wetsuit, the colder it can get before you start feeling uncomfortable; however, ensure that the temperature rating matches the activity you plan on doing!

What is a wetsuit?

A wetsuit is a neoprene insulation suit for warmth and protection in watersports. The suit works by trapping a thin layer of water between your body and the water, and this layer of water helps to keep you warm and protected from the elements. How do wetsuits work? A wetsuit traps a layer of water between your body and the water, and this layer of water helps to keep you warm and protected from the elements.

How Do Wetsuits Work?

A wetsuit is a piece of clothing made of neoprene, rubber, or other waterproof material. A wetsuit’s essential thing to keep us warm is this: the wetsuit catches a thin layer of water between our skin and the neoprene. Body heat wicks away the water, and the neoprene helps to keep us warm by trapping body heat.

How Should A Wetsuit Fit?

Wetsuit manufacturers typically recommend that a steamer wetsuit fit like a second skin with no sagging in the back or excessive bunching in the arms or legs. It should fit tight to keep on. A loose, saggy wetsuit will increase drag and slower swimming speed. A snug-fitting wetsuit also reduces water loss from evaporation, which is especially important when swimming in cold water environments. Wearing a properly fitting wetsuit can also help reduce the risk of hypothermia.

Choosing Wetsuit Thickness & Temperature

Wetsuit warmth is one of the essential aspects when considering a wetsuit. The thickness of the neoprene material determines how warm the suit will be. Wetsuits come in various thicknesses, from extremely thin to very thick. While thicker suits are warmer, they can also be more cumbersome and less flexible. Choosing the right thickness for your needs is essential, based on the water temperature where you plan to swim. 

Thin Suits are best for mild climates and cool water temperatures, while thicker suits are better for colder and hotter climates. There is no single perfect wetsuit thickness for everyone; it depends on your specific body type, swimming ability, and climate.

Wetsuit thickness and wetsuit water temperature

A wetsuit’s thickness is typically measured in millimeters, with the torso measurement of 3 mm and the legs 2 mm. When specifying a wetsuit, it is essential to know the water temperature in which the wearer will be using it. For example, a wetsuit designed for cold water at 32 degrees Fahrenheit would have a thickness of 3 mm on the torso and legs. However, if the wearer plans to swim in hot water at 108 degrees Fahrenheit, they would need a suit with a thicker thickness- 5 mm on the torso and legs.

What is a good thickness for a wetsuit?

A 3mm or 2mm shorty for summer surfing will be fine. A 3mm fullsuit with watertight seams is a better choice for dawn patrols and later spring and early Autumn surfing. For winter surfing wetsuits, a 4mm suit is recommended.

How cold is a 5mm wetsuit good for?

Wetsuits come in a variety of thicknesses and insulation levels. The most common type is a 5mm wetsuit, suitable for temperatures between 40 and 50 degrees Fahrenheit. A thicker wet suit can protect you from colder temperatures, but it can also be more cumbersome and difficult to swim in. A 3mm or 4mm wetsuit is suitable for temperatures between 30 and 35 degrees Fahrenheit, while a 1mm wetsuit is suitable for temperatures below 25 degrees Fahrenheit.

When choosing the perfect wetsuit thickness for your water temperature, it’s essential to understand that not all wetsuits are created equal. For example, a 5mm wetsuit is suitable for temperatures between 10 and 25 degrees Celsius (50-77 degrees Fahrenheit), while a 7mm wetsuit is suitable for temperatures between 15 and 30 degrees Celsius (59-86 degrees Fahrenheit). And don’t forget: always test a new suit in the water before hitting the waves!
