Belize Diving: To Wetsuit Or Not To Wetsuit?

Belize's water temperature is fairly consistent all year round, ranging from 77–84°F (26–29°C). While this is warm, some people might get chilled after prolonged exposure. Wetsuits are optional, with 2–3mm shorty wetsuits being the most commonly used. Rash guards are also often used as an alternative to wetsuits, as they protect against the sun, although they do not provide thermal protection.

Water temperature in Belize ranges from 77-84°F (26-29°C)

Water temperatures in Belize typically range from 77–84°F (26–29°C), making it a popular destination for divers and snorkelers all year round. The water is warm and inviting, with a comfortable temperature for swimming and water activities.

During the winter months, from November to March, the water temperature in Belize ranges from 77–78°F (26–27°C). It is recommended to wear a full 3mm wetsuit during these months to stay comfortable while diving or snorkelling. The water temperature starts to rise in April, marking the beginning of summer in Belize.

The summer months, from April to October, offer warmer water temperatures ranging from 83–84°F (28–29°C). This is an ideal time for swimming and snorkelling, as the water is pleasant and inviting. Even in the warmest months, a thin 2mm "shorty" wetsuit is often used by divers to provide a little extra warmth and protection.

The water temperature in Belize rarely dips below 77°F (26°C), making it a great destination for water activities all year round. The warmest water temperature is usually in September, with an average of around 85.5°F (29.7°C). Even in January, the coldest month, the average water temperature is a comfortable 79.3°F (26.3°C).

The consistent water temperatures in Belize make it a popular choice for divers and snorkelers, who can enjoy the clear waters and explore the diverse marine life without worrying about extreme temperature changes. The water temperature also affects the overall climate in Belize, contributing to the warm and tropical weather that the country is known for.

3mm wetsuits are commonly used in winter

Belize's water temperatures are fairly consistent all year round, ranging from 77-84°F (26-29°C). This means that wetsuits are optional for divers. Commonly used wetsuits in Belize are 2mm shorty wetsuits, with 3mm shortie or full wetsuits for those more susceptible to the cold.

Now, 3mm wetsuits are commonly used in winter in places with water temperatures of 15°C. They are perfect for average water temperatures in the UK between July and October. In the UK, 3mm wetsuits are used in the summer, with 6mm wetsuits being used in the winter. In Europe, 4/3mm wetsuits are used in the winter, with 5/4mm wetsuits being the most common. In the UK, 5mm wetsuits are used in the winter, with 3mm wetsuits being used in the summer.

The thickness of a wetsuit depends on the water temperature and the user's tolerance to the cold. The thicker the wetsuit, the warmer it will be. However, thicker wetsuits are also less flexible. The torso area of a wetsuit will usually be thicker to maintain core body heat, while the arms and legs will be thinner to allow for more flexibility.

So, while 3mm wetsuits are commonly used in winter in the UK, they may not be sufficient for colder temperatures in other parts of the world.

Rash guards are an alternative to wetsuits

The water temperature in Belize ranges from 77–84 °F (26–29 °C) all year round. While wetsuits are commonly used, they are not necessary. If you feel you would be more comfortable with a wetsuit, 2–3 mm shorty wetsuits are available for men, women, and children. Long wetsuits are also available for those who get cold easily.

Rash guards are often used as an alternative to wetsuits. They do not provide thermal protection, but they do protect against the sun. Rash guards are available in men's and women's sizes for those who feel more comfortable without a wetsuit.

Rash guards are a good option for divers who want to avoid sun exposure. They are typically made from lightweight, breathable fabrics that prevent moisture buildup. Some rash guards are designed to be worn under drysuits, with features such as elasticated thumb loops to keep the garment in place. Long-sleeve rash guards are recommended for divers to protect against sunburn and stings from jellyfish and fire coral. They also reduce the need for sunscreen, which can be beneficial for both your skin and the ocean.

Rash guards are available from various manufacturers, including O'Neill, Roxy, Fourth Element, Waterproof, Mares, Dakine, Scubapro, and Seac. When purchasing a rash guard, it is important to consider the fit. A tighter, more form-fitting rash guard may be more suitable for scuba diving, as it can be worn comfortably under a wetsuit. Loose-fitting rash guards are also available and can be a good option for those who want to stay cool.

A wetsuit can protect against jellyfish stings

Belize is known for its temperate and clear waters, making it a popular destination for divers and snorkelers. The water temperature is fairly consistent year-round, ranging from 77-78°F (26-27°C) in the winter months to 82-84°F (27-29°C) in the summer. While wetsuits are not necessary for thermal protection, they can still be useful for protecting against jellyfish stings.

A wetsuit can be an effective form of protection against jellyfish stings. Jellyfish release venom from their tentacles when they come into contact with skin, resulting in a range of symptoms from skin irritation to acute pain, breathing difficulties, and even death in severe cases. Wearing a wetsuit creates a barrier between your skin and the jellyfish, as the tentacles cannot penetrate the thicker material.

The thickness of a wetsuit plays a role in providing protection against jellyfish stings. While a thinner wetsuit, such as a 2mm or 3mm shorty wetsuit, may be sufficient for thermal protection in Belize, a thicker wetsuit is recommended for sting protection. A 3mm full wetsuit or a rash guard can provide better coverage and reduce the risk of exposure to jellyfish stings.

In addition to the thickness of the wetsuit, it is important to ensure that it fits properly and covers as much skin as possible. Jellyfish can still sting you if there is direct skin contact, so make sure the seals of the wetsuit are tight, especially around the neck and wrists. It is also crucial to rinse off after a dive to remove any stinging cells that may have collected on the wetsuit.

While a wetsuit can provide protection against jellyfish stings, it is not a guarantee. Some highly venomous species, such as cone snails, may still be able to penetrate thicker neoprene. Therefore, it is important to be cautious and avoid touching anything in the water whenever possible.

A shorty wetsuit can be rented

The water temperature in Belize ranges from 77-78°F in winter to 83-84°F in summer, with a fairly consistent average of 79 to 84°F (26-29°C) all year round. This means that wetsuits are optional for diving in Belize.

If you are susceptible to the cold, you may want to consider renting a shorty wetsuit. Shorty wetsuits are a versatile and flexible option, providing thermal insulation and allowing greater mobility. They are designed for water activities in warm to moderately cool conditions, making them ideal for scuba diving in Belize.

Shorty wetsuits are cropped at the legs and/or arms and are made using thin neoprene to keep you at the right temperature. They are lightweight and stretchy, so you won't overheat, and they also provide UV protection and windchill defence. Shorty wetsuits are available in a range of sizes for men, women, and children.

If you tend to get cold easily, you may prefer to rent a long wetsuit for your diving trip to Belize. Alternatively, a rash guard can be worn as an alternative to a wetsuit, although it does not provide thermal protection.
