The answer to this question depends on the type of Frisbee you are using. If you are using a standard plastic Frisbee, then a moderate amount of wind is fine. However, if you are using an aerodynamic Frisbee, then too much wind can be a problem.
If you are playing with a group of people and the wind is blowing strongly, it can be difficult to keep the Frisbee from going off course. In addition, if the wind is gusty, it can be hard to control the Frisbee. If you are playing by yourself, strong winds can make it difficult to throw the Frisbee accurately.
In general, moderate winds are fine for playing with a standard plastic Frisbee. However, if the wind is strong or gusty, it may be best to find another activity to do instead.
