Patagonia's weather is dry and sunny most of the year, with low air pressure because of its desert climate. High pressure systems bring clear skies and little rain.
Mountains surrounding Patagonia block moisture from the Pacific Ocean, keeping the air dry and pressure low. This creates a "rain shadow" effect.
In summer, high pressure dominates, making it hot and dry with very low pressure. Winter brings low pressure, making it cooler and wetter, but still dry overall.
Patagonia's desert climate means low air pressure and clear skies most of the time. This leads to hot summers and mild winters with very little rainfall.
