Global and Indian climate classification.
| Region | Major climate group | Temperature (warmest month) | Temperature (coolest month) |
| Global, according to Koppen–Geiger Theory [55] | Tropical | >18°C | >18°C | Dry | ≥18°C | ≤0°C | Temperate | ≥10°C | ≥ −3°C and <18°C | Continental | ≥10°C | ≤ −3°C | Polar and alpine | ≤10°C | ≤0°C | Highland | Temperature is highly dependent on adjacent zone traits and overall elevation | |
| Region | Major climate zone | Mean of monthly temperature | Mean of monthly relative humidity |
| Asia (India), according to NBC 2016, India [30] | Hot and dry | >30°C | <55% | Warm and humid | >30°C > 25°C | >55% > 75% | Temperate | 25–30°C | <75% | Cold | <25°C | All values | Composite | When 6 months or more do not fall in any of the categories | |
