Usually the climatic conditions of Goa are temperate, except during the monsoons, which last from June to September. Thanks to the coastal Konkan region, and the backdrop of the Western Ghats, the weather of Goa is pleasant and sunny.
There are no extremes of temperature and no clear demarcation from one season to the other, except for the monsoons.
The average temperature varies between 23 degrees Celsius and 32 degrees Celsius. The average rainfall is approximately 250 cm and the average daily hours of sunshine are 9 to 10 hours in summer and 3 to 5 hours in the monsoons.
The main feature of the Goan climate is the monsoon which occurs between June and the end of September. Goa lies in the path of the South Westerly Monsoon thereby experiencing a dry period lasting 6 to 8 months of the year followed by the annual rainfall which occurs over the remaining four months.
During the two months preceding the onset of the monsoon, the humidity increases dramatically and the normally clear skies become hazy and then cloudy. During the monsoon 200 cm to 250 cm of rain is normal, although in the Western Ghats the downpour is considerably higher than on the coast.
Once the monsoon has run its course the skies clear up and the weather becomes pleasant. For 4 to 5 months from October through February, the climate is near perfect, cloudless blue skies, warm but not oppressively hot days and calm seas. By mid-March the humidity starts to rise as the monsoons begin to approach again.
