Why Is Perth So Hot?

Four Contributing Factors

1. Latitude & Indian Ocean Dipole: West coast location in a tropical-influenced zone.
2. Ocean Currents (ENSO Link): El Niño phases warm the Indian Ocean Dipole, raising Perth temps.
3. Land-Sea Breeze: Daytime heating draws humid sea breezes; moderates but adds moisture.
4. Urban Heat Island: Concrete/asphalt absorb and re-radiate heat, making the city warmer than surroundings.

These combine to make Perth one of Australia's hottest major cities.
