No! A common misconception is that swimming in winter can cause colds, when actually children are no more likely to catch a cold from swimming during winter than during summer.
Drying off and rugging up after lessons is a sure fire way to enjoy swimming all year round!
Taking a break in winter means regressing in skill retention for summer. Remember, consistency is an important component of skill acquisition.
The progression rate of swimming skills is determined by how often kids participate and practice.
