Understanding Humidity in Kerala: Why It Feels So Hot

Kerala's climate is heavily influenced by its location along the southwest coast of India and its proximity to the Arabian Sea. While temperatures are often moderate compared to some inland regions of India, the high moisture content in the air can make the weather feel significantly warmer.

What Is Humidity?

Humidity refers to the amount of water vapor present in the air. When humidity levels are high, sweat evaporates more slowly from the skin, reducing the body's natural cooling mechanism. This is why a day with a temperature of 32°C can feel much hotter when humidity is high.

Why Is Kerala So Humid?

Several factors contribute to Kerala's humidity:

1. Coastal Geography – Moist air from the Arabian Sea constantly moves inland.
2. Monsoon Seasons – Heavy rainfall increases moisture in the atmosphere.
3. Dense Vegetation – Forests and agricultural land release water vapor through transpiration.
4. Tropical Climate – Warm temperatures allow the air to hold more moisture throughout the year.
