Forecast

White Salmon has changing air pressure due to its location near the Columbia River and surrounding mountains. Air pressure drops when low-pressure systems move in, often bringing rain. The city's geography, with mountains to the east, blocks some weather patterns and creates a rain shadow effect. In winter, high pressure builds, bringing cold and clear skies. Spring and fall have low pressure, leading to more rain and wind. Summer has high pressure, resulting in warm and dry conditions. White Salmon has an oceanic climate, with significant rainfall throughout the year. The nearby river helps regulate temperatures, keeping them relatively mild. Low-lying areas near the river experience fog during winter months. The climate type leads to pressure changes, causing varied weather patterns. Winds from the west bring moisture, influencing air pressure and weather. Seasonal changes impact air pressure, affecting local weather conditions. Mountains and river create a microclimate, altering pressure and weather patterns. These factors make White Salmon's weather unique and diverse.
