Tropical nights, summer days and heat days are good indicators to classify heat and possible heat stress during summer:
- Summer day (orange): summer days are classified as days with a maximum daily air temperature of more than 25 degrees. Summer days can cause heat stress especially among elderly and sick people.
- Heat day (red): heat days are classified as days with a maximum daily air temperature of more than 30 degrees. Heat days can cause severe heat stress for most people.
- Tropical night (blue): tropical nights are classified as nights (from 6 pm to 6 am) where the minimum air temperature does not drop below 20 degrees. Tropical nights can cause severe heat stress due to insufficient recuperation at night.
