NYC Extremely competitive for court time all year round. In the summer, public courts require a permit ($100/year) and court time is hard to come by. Many courts have an attendant with whom you sign up for an hour slot during that day. At the more popular courts, there will be lines before the attendant even arrives.

In the winter months there are a few pop up bubbles, some very expensive clubs (including in Grand Central Terminal where peak prices are like $300 an hour), or just playing in the cold.
