There are two distinct seasons in Kollam. A relatively dry season lasts from approximately December to February, characterized by minimal precipitation (about 1 mm in January and February) and few rainy days. Starting from March-April, rainfall and rainy days gradually increase, transitioning into a pronounced monsoon season, which peaks from May to October. Significant rainfall occurs during this period (up to 12 mm in May), and almost every day can be rainy, especially from May to July, when the number of rainy days reaches 30 per month.

The climate in Kollam is characterized by high temperatures throughout the year, typical of southern India. The annual range of average temperatures is relatively small: the "coolest" months, July and August, show an average temperature of about 26.4°C, while the hottest month, April, reaches an average temperature of 29.0°C. Thus, the variation in average monthly temperature is only about 2.6°C. The hottest period occurs in March and April, when maximum daytime temperatures can exceed 31.7°C, and in March even 32.1°C.

The "winter" season, from December to February, offers the most comfortable weather: days are warm, with average temperatures of 27-28°C and highs around 30-31°C, while nights are mild. Diurnal temperature fluctuations in Kollam are moderate. In drier months, such as January-March, the difference between the daytime maximum and nighttime minimum is about 6-7°C. During the monsoon period (roughly from May to October), due to high humidity and cloud cover, this difference narrows to 3-4°C, keeping it warm even at night.

When planning a trip to Kollam, it's important to consider its warm and humid climate, which persists throughout the year. The average annual temperature fluctuates within a comfortable range of 26-29°C, so the basis of your wardrobe should be light, breathable clothing made from natural fabrics like cotton or linen. Don't forget sunscreen with a high SPF, a hat or cap, and sunglasses to protect against the bright Indian sun. Comfortable walking shoes, such as sandals or lightweight sneakers, will be indispensable for exploring the city and its surroundings, especially since you'll be doing a lot of walking.

Kollam is characterized by a pronounced rainy season spanning approximately from April to November, with the highest rainfall (from 5 mm to 12 mm per month) and the maximum number of rainy days (almost daily from May to October) occurring during these months. At this time, a light umbrella and a compact raincoat will be indispensable companions. Opt for clothing made of quick-drying materials. Although temperatures remain high year-round, a light sweater, shawl, or stole can be useful for sun protection, the evening cool near the water, or when visiting air-conditioned spaces. In the drier months, like January and February (with minimal rainfall and only 5-7 rainy days), the need for a raincoat decreases, but a compact umbrella still won't go amiss in case of an unexpected shower.
