India's early intense heatwave sees Banda Prayagraj, Maharashtra exceed 45°C

Heat dome and anticyclone prolong heat

This spike isn't just your regular summer: it's mostly thanks to a heat dome, where high pressure traps hot air near the ground.
This keeps skies clear and lets sunlight pour in without much relief.
Because of this effect (and an anticyclone over Maharashtra), these extreme temperatures are sticking around longer than usual.
