Weather and climate in Guwahati (Assam)

The climate of Guwahati (or Gauhati) is subtropical, with pleasantly warm, dry winters from November to February and a long, hot and rainy period from April to mid-October. The monsoon runs from roughly from June to early or mid-October, but showers occur in April and May (and more rarely in March), which gradually become more frequent.
The city is located in northeastern India, in the state of Assam, on the banks of the Brahmaputra River. About 70 km (43 mi) to the north are the first spurs of the Himalayas (in Bhutan and in the Indian state of Arunachal Pradesh), while just to the south is the Shillong plateau, in the small state of Meghalaya, whose mountains, in the south, are one of the wettest areas in the world. These mountains partly protect Guwahati and its area, to the point that rainfall is lower than 1,800 millimeters (70 inches) per year.
Since we are outside of the Indian continental mass, the warming from March to May is reduced, also because the rains begin earlier. As a result, on average, the hottest period is from June to August. However, the records were recorded from late April to early June here as well. In late April 2014, the temperature reached 40.6 °C (105.1 °F). In any case, in periods of good weather it can be very hot even from July to September.
In winter, from mid-November to late February or early March, nights are cool, and sometimes even cold. Cold records are around 5 °C (41 °F).
In addition, from November to January, fog can form at night and in the early morning.



Guwahati is in the path of tropical cyclones, which come from the Bay of Bengal, usually from mid-April to early December. In general, they are most intense either at the beginning and the end of the period, that is, in May-June and October-November. Since we are far from the coast, the city is not hit by cyclones at full strength, however, they can bring heavy rainfall.
