Antofagasta is a coastal desert city in Chile. Its air pressure is high due to the Pacific High, a high-pressure system that sits over the Pacific Ocean.
The city's geography, being surrounded by the Pacific Ocean and the Andes Mountains, blocks moisture from entering, making the air very dry.
In summer, the air pressure is lower due to the South Pacific High moving north, allowing cooler air to enter. In winter, the air pressure is higher as the high-pressure system moves south.
Antofagasta has an arid desert climate, which means very little rainfall. The high air pressure from the Pacific High and the city's geography traps dry air, keeping the climate hot and dry.
