Lightning News & Analysis – India

All 28 States + 8 Union Territories

State pages are prepared but deliberately kept out of Google until verified state-specific lightning data and dates are added. This protects the site from thin or unsupported scaled content.

Lightning Activity

Occurrence or density where reliable data is available, thunderstorm activity, seasonal pattern, monsoon and pre-monsoon behaviour and significant events.

Engineering Relevance

Industrial, solar, substation, railway, airport, hospital, telecom and warehouse lightning protection applications.

Worldwide Analysis

Global hotspots, significant events, loss context, risk reduction, IEC 62305, earthing and SPD with source/date attribution.
