How do you decide when the weather is too hot, cold, or risky for walking your dog?

I’m curious how other dog owners decide when the weather is too hot, cold, or risky for walking their dog. Do you mostly go by temperature, rain, wind, breed, age, or just experience?

It’s something I kept thinking about, so I made a small free tool around it: https://gooutsidedog.com/⁠

Would love to know how you currently make that decision, and whether a tool like this would actually be useful or not.
