Yangon (Rangoon), Myanmar's largest city, sits on the Yangon River in the Irrawaddy delta region of the south, on low ground near the Andaman Sea at approximately 16.87°N, 96.20°E. It has a tropical monsoon climate (Köppen Am) — hot and humid — with the three Burmese seasons: a cool winter, a hot summer, and a drenching monsoon.

The hot season, from March to April, is the most punishing, with highs around 36–38°C and rising humidity under hazy skies. The southwest monsoon then bursts in around May and runs to October, bringing torrential, near-daily rain — June, July and August are drenching — with thick cloud and oppressive humidity, though the rain moderates the temperature considerably.

The cool season, from November to February, brings warm, dry, sunny days around 32–33°C and comfortable nights near 18–20°C, with low humidity and virtually no rain. This bright, mild, dry stretch is comfortably the best time of year and the peak season for travel across the country.

Yangon is very wet, receiving on the order of 2,500–2,700 mm of rain a year, overwhelmingly delivered by the southwest monsoon between May and October, when the delta region is drenched, while December to February is nearly rainless. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Yangon sits on the low, densely populated Irrawaddy delta, which is dangerously exposed to the cyclones that form in the Bay of Bengal, most often just before and after the monsoon. Cyclone Nargis devastated the delta in May 2008 with a catastrophic storm surge, one of the deadliest natural disasters in the country's history.
