Coimbatore, located in India, is distinguished by a predominantly tropical climate, characterized by warm and hot weather throughout the year. Temperature fluctuations between seasons are not too great, making the city attractive to visit at various times; however, the distribution of rainfall should be taken into account.

Two main seasons can be distinguished in Coimbatore. The dry and hot period usually lasts from January to April, when rainfall is minimal and daytime temperatures can reach their peak, especially in March and April. From May to November comes the monsoon season, bringing with it most of the annual rainfall. During this time, the number of rainy days increases, and the air temperature becomes slightly more moderate thanks to cloud cover and rain.

The most pronounced rainy season falls on the months from June to October, when the amount of precipitation and the number of rainy days are at their maximum. During this period, the weather can be quite humid. December marks the transition to a drier period, with decreasing rainfall and comfortable temperatures, making it and the subsequent months leading up to the rainy season a popular time for visits.

Coimbatore experiences a warm climate year-round, yet temperature indicators have their own seasonal specificities. The average annual temperature fluctuates within a comfortable range, but the peak heat occurs during the spring months. The hottest month is usually April, when the average temperature reaches 27.4°C, and maximum daytime values can rise to 32.7°C. It is slightly cooler, but still very warm in March, with an average temperature of 26.0°C and highs up to 31.7°C. The coolest month is considered to be January, with an average temperature of 22.0°C, while minimum night-time temperatures can drop to 17.2°C, creating a pleasant coolness.

The summer period, especially from March to May, is characterized by hot weather. Daytime temperatures consistently exceed 30°C, and in April even 32°C. Nights bring some relief but remain warm, with minimum temperatures around 20-22°C. With the arrival of the monsoons from June to September, although the warmth remains, average maximum temperatures decrease slightly to 27-28°C, and average minimums hold around 20-21°C. Winter months, such as December and January, offer the mildest weather. During the day, the temperature stays at a comfortable level of around 26-27°C, while nights become noticeably cooler, with temperatures dropping to 17-18°C. This creates a pleasant contrast and makes the winter period particularly comfortable for walks and outdoor activities.

Temperature fluctuations between day and night in Coimbatore are quite noticeable throughout the year. The difference between the average maximum and average minimum temperature is often around 9-11°C. For example, in January the difference is almost 10°C (26.8°C max and 17.2°C min), and in April – about 10.5°C (32.7°C max and 22.2°C min). This means that even in the hottest months, evenings and early morning hours can bring refreshing coolness, while winter nights can be quite fresh, requiring light warm clothing.

In Coimbatore, fairly clearly defined seasonal changes in rainfall patterns are observed. The year can be roughly divided into a dry period and a rainy season, which is important to consider when planning a trip to this region of India.

The dry season in Coimbatore usually falls on the months from January to March. At this time, rainfall is minimal – only about 1 mm per month. January, February, and March are characterized by a low number of rainy days: 7, 3, and 4 days respectively. February stands out as the driest month with the fewest days with precipitation. In April, the amount of rainfall increases slightly to 2 mm, and the number of rainy days rises to 9, heralding the change of season.

The rainy season begins in May, when rainfall increases to 5 mm, and the number of rainy days rises sharply to 21. The most intensive and frequent rains are observed from June to October. August is the month with the maximum average rainfall (8 mm), and July is the month with the highest number of rainy days (on average 26 days). In June, September, and October, a significant amount of rainfall (6-7 mm) and a large number of rainy days (about 24 days) are also recorded. It is important to note that although it rains often in these months, the total amount of precipitation remains moderate, which may indicate a prevalence of not too intense, but regular rains. From November, the amount of rainfall and rainy days begins to decrease (5 mm and 19 days), and in December this process continues (2 mm and 12 days), marking the transition to a drier period.

When planning a trip to Coimbatore, it is important to consider its tropical climate with warm temperatures year-round and a pronounced rainy season. The basis of your wardrobe should consist of light and breathable fabrics, such as cotton or linen, which will help you endure the heat comfortably. Regardless of the season, be sure to bring sunscreen with a high SPF, sunglasses, and a hat for protection against the intense sun. Comfortable walking shoes are another must-have, as you will likely be moving around a lot while exploring the city.

From January to April, especially in March and April, when daytime temperatures reach their peak (up to 32.7°C), preference should be given to the lightest possible clothing. However, considering the noticeable difference between day and night temperatures (minimums can drop to 17-22°C depending on the month), a light cardigan or shawl may be useful for evening walks, especially in the "cooler" months such as January or December. In the period from May to November, and especially intensively from June to October, Coimbatore experiences the rainy season. At this time, it is highly recommended to have an umbrella or a light waterproof jacket with you. Clothing made from quick-drying materials will also be very handy. Although the amount of rainfall is not extremely high, rains can be frequent (up to 26 rainy days in July), so be prepared for increased humidity.

The principle of layering clothing is an excellent strategy for Coimbatore at any time of the year. This will allow you to easily adapt to temperature changes throughout the day: from warm daytime weather to cooler evenings. For example, a light long-sleeved shirt can serve both as sun protection during the day and as an extra layer in the evening. Don't forget insect repellent as well, especially if you plan trips to nature or walks in the evening during the rainy season.
