Officials of the Regional Meteorological Centre (RMC) say abnormal heatwave conditions persist across Tamil Nadu and are expected to continue until July 17. They attribute the spell to weak monsoon circulation over the Southern Peninsular region and atmospheric conditions linked to El Niño. According to the RMC, these factors reduce cloud formation, which in turn allows unusually high temperatures to continue through the period. Multiple reports also indicate that rainfall conditions are expected to improve later in the week, suggesting a possible easing of the heat as moisture and cloud activity increase. The forecast is presented as an outlook for the coming days, with officials noting that monsoon-related circulation and broader atmospheric drivers are influencing local weather patterns. Residents across the state are therefore advised to be prepared for sustained high temperatures until the stated date, while expecting more favorable weather as rains develop later.
