8 am 11 am 5 pm

Also see live temperature map.

These maps show how air temperatures changed in the United States over the course of one October day, from 8 am to 5 pm. Monarchs can't fly if their flight muscles are too cold. As a general rule, they need air temperatures of at least 50°F on a sunny day or 60°F on a cloudy day.

  • Describe where and when is it too cold to fly on this October day. Assume there were no clouds.

 

  • What's happening right now?
    Link to the live air temperature map for the United States. Where is the air temperature warm enough for monarchs to fly right now?
