Forecast

The barometric pressure in Oaxaca City is typically high. It averages 767 mmHg. This is due to its location in a valley.

Oaxaca City is surrounded by mountains. The Sierra Madre del Sur mountain range is to the south. The Sierra Norte mountain range is to the north.

These mountain ranges create a valley that traps air. This trapped air leads to a higher pressure. The surrounding mountains also block air from the Pacific Ocean.

As a result, the air in Oaxaca City is dry. It comes from the north, not the ocean. This dry air contributes to the high pressure.
