Winter Swimming in Hong Kong: Embrace the Chill!
We are fortunate that swimming in Hong Kong can be a year round activity. The heated indoor public and private pools that we use are kept at a constant 28 - 29C.
Swimming is a year-round activity, and with the right preparations, you can enjoy it even in the coldest months.

While it may seem daunting to plunge into the water when temperatures drop, embracing the chill can lead to significant physical and mental resilience.
Building Cold Tolerance
Even as a seasoned swimmer, stepping into water when the air temperature is cool, is always uncomfortable. The initial step in always feels cool, even when the pool temperature is warmer than the air temperature! Over time, the tolerance of cooler temperatures and discomfort increases.
The Importance of Thermal Wear
Who Should Wear Thermal Gear?
For beginner swimmers, particularly those in Baby & Tots classes, Children in Strokes 1 and below, and Adult Basic & Beginner levels, thermal wear is essential when air temperatures drop. Although public pools maintain a warm temperature, many swimmers may not generate enough body heat for comfort during lessons.
Optimal Conditions
Our indoor facilities are maintained at 29°C, while public pools are set to 28°C from November to Easter. It is advisable for young swimmers to wear thermal gear starting in October until the weather warms up significantly. Children may be less tolerant of cooler water compared to summer, and comfort is crucial for effective learning.
The Role of Comfort in Learning
When children are focused on staying warm, they cannot fully concentrate on swimming. Ensuring that they are comfortable allows them to engage more effectively in lessons. If a child appears too cold to focus, it’s important to take them out of the water promptly. This approach prioritizes positive experiences over the duration of the lesson.
Choosing the Right Thermal Wear
Wetsuits vs. Rash Guards
Understanding the difference between wetsuits and rash guards is vital. Wetsuits, made from neoprene, retain heat by trapping a thin layer of warm water against the skin, while rash guards primarily offer sun protection and can even cool the body down by retaining moisture.

For optimal warmth, look for neoprene water thermals with a thickness of 2.5mm or 3mm. Ensure a snug fit; loose-fitting wetsuits do not provide adequate insulation.

Important Safety Tips
Always monitor your child for signs of discomfort. If they start shivering uncontrollably or turning blue, remove them from the water immediately and shower them with warm water. Thermal wear should only be removed in a warm shower to prevent discomfort from exposure to cold air.
Conclusion
Winter swimming can be a fun and rewarding experience for everyone involved. By ensuring warmth and comfort, your child can focus on learning and enjoying their time in the water. Let’s make this winter swimming season the best one yet!
