How we ranked these

We benchmark each month against a basket of heat-prone cities (NYC, Paris, Rome, London, Madrid, Tokyo, LA, Atlanta, Miami) and only include destinations at least 4°C cooler than that average. Then we tier by comfort:

Cities in peak hurricane / monsoon season are deprioritized — being cool isn't worth it if you're stuck indoors.
