Thiruvananthapuram, widely called Trivandrum, is the capital of Kerala and a coastal city with a tropical monsoon climate that holds 27°C or more every month of the year. Tucked between the Arabian Sea and the Western Ghats’ foothills, it runs hot and humid through all seasons, with two distinct monsoons, the heavy southwest monsoon from June to August and a lighter northeast monsoon in October and November, and a reliably dry, sunny high season from December to February. Before booking, read the best neighborhoods guide to decide between the Fort, Palayam and the coastal strips. Days peak around 33°C in March and April and the sea stays swimmable at 27-30°C year-round.
Welcome to Thiruvananthapuram
A city of about 1 million people, Trivandrum is one of south India’s main travel hubs, framed by the Sree Padmanabhaswamy Temple at its old core and fanned out along the coast to the famous Kovalam Beach 16 km south. Most arrivals land at Trivandrum International Airport (TRV), just 6 km from the centre, then split their time between the temple-and-palace quarter around East Fort, the museum and park district of Palayam, and the three crescent beaches of Kovalam. Use the month-by-month weather data below to pick your travel window, then dive into the specialist guides.

Location and Climate Setting in Thiruvananthapuram
Trivandrum sits at 8.5° north latitude on Kerala’s southwest coast, roughly 90 km from the southern tip of India at Kanyakumari. The Western Ghats rise behind the city and intercept the southwest monsoon, which is why the surrounding region is among the wettest in India, while the coastal strip itself stays warm and sea-moderated. Inland day trips climb quickly into cooler hill stations like Ponmudi at 915 m and the Agasthyamalai peaks.
