First and foremost, I would contact the school with your concerns. If it is a concern of multiple parents and the school does not respond, it would be a good idea to attend a board meeting. It is possible that there is a standard that has to do with the temperature outside and when it is too hot/cold to have the children play.
Check out the website that I have attached. It talks about outside play and how long children should play under certain conditions. I hope this helps!
