Swimming School During The Nine Days
One should avoid swimming during all of the nine days.
If your children are under the age of Chinuch (2-5 years old) there is room for leniency for swimming lessons.
If it isn’t possible to find another opportunity for swimming lessons, we can be lenient even up to 10 years old.
This is so especially where cancellation will cost money.
Nonetheless, many are particular to avoid any activities which are unsafe during this period.
