For recreational/traveling teams in U9-U14, the spring season usually starts late March/Early April for practices and the first game in mid-April. This is very dependant on the weather and field conditions. Games typically go to mid-June, but most coaches try not to go past Memorial Day.
For in house U5-U8 soccer, practices/scrimmages are twice a week normally Tuesday and Thursday, from 5-6 to 5:30-6:30 next to the concession stand. This program usually runs 6-7 weeks starting the beginning of April to the end of May
