About Thiruvananthapuram weather
Thiruvananthapuram is one of many towns in Kerala's narrow, entirely coastal-influenced strip between the Arabian Sea and the Western Ghats, about 54 km south-east of Kollam. Before the rains arrive, there's a warm, humid pre-monsoon season (March–May) with highs typically in the low-to-mid 30s°C. After that, Thiruvananthapuram sees two rainy seasons — a heavy south-west monsoon (June–September) that's usually India's first monsoon landfall, and a lighter north-east monsoon (October–November). Cooler months mean a mild winter (December–February) that stays warm and humid by most of India's standards.
