Charleston, Oregon, lies beside the Pacific and the mouth of Coos Bay, where ocean air keeps temperatures fairly mild. From fall through spring, low-pressure storms often arrive from the ocean, bringing clouds, steady rain, and gusty winds to the coast.
As these storms pass, pressure falls ahead of them and rises behind them. Winds shift as fronts move through. In summer, stronger high pressure over the North Pacific often guides storms north, while cool marine air can leave the shoreline cloudy or foggy.
Nearby headlands and coastal hills shape exposure. Open beaches face ocean winds, while sheltered parts of the bay may feel calmer. Winters are wet and cool; summers are usually mild, with little rain. Spring and autumn bring frequent clouds and changing rain.
