Annual Water Temperature Trend

Manzanita, on the northern Oregon coast, fronts the cold Pacific and the waters there follow the cool patterns typical of this region. Sea surface temperatures near the shore generally range from about 7–10°C in winter, rising gradually through spring to roughly 8–11°C. Summer brings the warmest conditions, with average nearshore temperatures typically around 11–14°C, and early autumn usually sees a slight cooling to roughly 9–12°C. These figures can vary year to year and with tides, currents and offshore upwelling, but they convey why the ocean at Manzanita feels brisk even on summer days.
