Are swim classes cancelled when it rains?
• In most instances, swim classes are held rain or shine. In the event of thunder or lightning, or when pool/lake water conditions are not appropriate for swimming, classes are cancelled, and notification is put on the Recorded Information Line at 617-796-1536. The decision cannot be made until approximately 8:30 AM, when the morning staff is on duty, and all testing of the pool and lake water and evaluations of the site and weather are completed.
