Goa enjoys moderate climate throughout the year. It never gets too hot in the summer or drop to the extremity during the winters. This is attributed to the location of the place.
Goa is located in the tropics on the western coastline of India with the Arabian Sea in the west and the Western Ghats in the east and the state of Maharashtra in the north and Karnataka in the south. Due to its proximity to the sea, the climate does get a bit humid and warm for most part of the year hovering mainly around 60%.
The climate of Goa is coastal with little variations in temperature during the season. In fact, Goa enjoys moderate temperatures throughout the year. The average temperature varies approximately between 25°C - 35°C (67.96F - 86.56F). The average rainfall is approximately 325cms and the average daily hours of sunshine is nine to ten hours in summer and three to five hours during the monsoon.
The climatic conditions in Goa can be divided roughly into three seasons:
Summer: Mid-March to May end (Min. 25C - Max. 35C)
Summer begins from mid March till May end reaching its peak in May. During this season, temperature varies from 25 to 35C. The heat is accompanied by high humidity and it increases dramatically especially during the two months preceding the onset of monsoon. The skies are clear during most of the summer. The average daily hours of sunshine is nine to ten hours during this season. Visitors avoid coming during summers.
Monsoon: June to September end (Around 26C)
Goa receives the full strength of the Indian monsoon from June to September end. This season is marked by sudden heavy downpours and tropical thunderstorms. Most of Goa's annual rainfall is received through the monsoons. The average rainfall received ranges from 250cm to 300cm. However, Western Ghats receives heavier downpour than on the coast around 400 cm annually. Goa is in the path of the southwest monsoon meaning that it experiences a dry spell of six to eight months before the annual rainfall which occurs continuously for four months. July receives maximum rainfall while February receives the least. The skies get hazy and cloudy during the monsoon but after it retreats, it becomes clear again and the weather becomes pleasant. The average daily hours of sunshine is three to five hours during the monsoon.
Winter: October to March beginning (Min. 3C - Max. 11C)
This is the beat time to visit Goa. During winter season from October to March, the temperature is more on the cooler side ranging from 3 to 11C. The cool temperature is accompanied by clear skies and calm seas. January and February are the coldest months in Goa. The interior parts of the state become significantly colder at night than the coastal areas due to rise in altitude. A strange phenomenon seen here is that day temperatures touch the lowest during the monsoon months of July and August and not during the winters.
