The anticipated impact of the El Niño climate phenomenon on Tamil Nadus Northeast Monsoon is raising concerns regarding the potential rainfall patterns in Chennai for the year 2026.

In Chennai, the implications of reduced rainfall could be serious, affecting both agricultural outputs and urban water supplies. Various stakeholders are advised to monitor updates from meteorological departments and consider water conservation measures in anticipation of possible lower rainfall during the impacted seasons.
