The weather department has indicated that Tamil Nadu is expected to receive above-average rainfall in November.

Additionally, temperatures in Tamil Nadu’s coastal districts may rise slightly by one to two degrees Celsius in the coming days due to changes in weather conditions.

As the northeast monsoon becomes active over Tamil Nadu, various regions in the state are expected to experience above-average rainfall in November. Additionally, temperatures may rise slightly by one to two degrees Celsius in the coming days, particularly in the coastal districts, due to changes in wind patterns over the sea.

A trough extending from a cyclonic circulation over the south Tamil Nadu coast and adjacent Sri Lanka to coastal Karnataka has prompted intense rainfall warnings for ten districts: Kanniyakumari, Tirunelveli, Thoothukudi, Tenkasi, Theni, Dindigul, Madurai, Virudhunagar, Sivaganga, and Ramanathapuram. Other parts of the state are forecasted to receive light to moderate rain.

Following this period of rainfall, a brief lull in activity is expected over the next three days. However, another cyclonic circulation is anticipated to form over the sea, potentially bringing rain to various parts of the state starting November 7.

Despite the expected rainfall, the changing wind flow patterns due to the system over the sea may lead to increased maximum temperatures along the coastal areas, including Chennai, although no significant spikes in temperature are predicted. Recently, Chennai and its suburbs have experienced moderate to heavy rainfall due to a trough affecting southern Tamil Nadu and adjoining regions.

For the next two days, wet weather is likely to persist, with maximum and minimum temperatures expected to be around 31°C and 25°C, respectively.

During the northeast monsoon season (October 1 to November 2), the state received 22 cm of rainfall, exceeding the normal amount of 18 cm by 21 percent. Coimbatore district recorded the highest rainfall, with 113 percent more than the average due to intense recent downpours. However, 13 districts, including Ariyalur, Chengalpattu, and Cuddalore, experienced a deficit in rainfall.
