Okanogan's weather is influenced by high and low air pressure systems, which bring different types of weather. When high pressure is over Okanogan, it means good weather with clear skies and warm temperatures.
The valley where Okanogan is located traps cold air, making it colder in winter and warmer in summer. This is because cold air is heavier and sinks, getting stuck in the valley.
In winter, low pressure brings cloudy, rainy, and snowy weather. In summer, high pressure brings sunny, hot, and dry weather. Spring and fall are mild with a mix of both.
Okanogan has a semi-arid climate, which means it's dry with low humidity. This is because Okanogan is in a rain shadow, blocked from getting much moisture from the Pacific Ocean by the Cascade Mountains.
