    General Weather Conditions in Portland, OR

    The coast range provides limited shielding from the maritime influence of the Pacific Ocean. The Cascade Range provides a steep high slope for the lifting moisture-laden westerly winds, which produces heavy rainfall in the western Cascade piedmont region. They also form the barrier for the Columbia River basin region and dry continental air masses. Airflow is usually northwest in Portland in spring and summer and southeast in fall and winter, interrupted occasionally by outbreaks of dry continental air east through Cascade passes and across ridge tops. When such an outbreak occurs, extreme high or low temperatures are usually experienced in the Portland area.

    Portland has a very definite winter rainfall climate. About 88 percent of the annual total occurs in October through May, nine percent in June and September, while only 3 percent comes in July and August. The average annual precipitation is 37.33 inches (948.2 mm). December is the wettest month, and July, the driest. Precipitation is mostly rain; on the average only 17 days each year have snow. Snowfall is seldom more than a couple of inches, and it generally lasts only a few days. The annual average is only seven inches (178 mm) with January having the most. Snowfall has fallen in every month from November through May. The greatest measured snowfall in 24 hours was just under 11 inches (279 mm) recorded in January 1971.

    Each season is clearly marked. Winter is mild, cloudy and wet with southeast surface winds predominating. Summer is marked by mild temperature, with prevailing northwest winds and very little precipitation. Fall and spring are transitional in nature, with frequent periods of ground fog. An average of 18 days during October record foggy conditions while only three days during July can expect fog. At all times, incursions of marine-tempered air are a frequent moderating influence. Outbreaks of continental air from east of the Cascade Mountains flow through the Columbia Gorge at near sea level and spread into the Portland area associated with the movement of Pacific storms offshore on a northeast storm track. In winter this brings the coldest weather, and the extremes of low temperature are registered in the cold airmass. Freezing rain and ice glaze often are transitional effects. In summer the hot, dry, continental air brings the highest temperatures. Extreme temperatures below zero are very infrequent. The absolute lowest ever reached is 3°F below zero (-19.4°C) recorded in February 1950. Extreme temperatures above 100°F (37.8°C) have occurred during each month from May through September; the absolute highest temperature is 107°F (41.6°C) recorded in July 1942, July 1965 and August 1981. Temperatures 90°F (32.2°C) or higher are reached every year, but seldom persist for more than 2 or 3 days before the warm spell is broken by a flow of cool, moist air from the ocean. The average annual temperature for Portland is 53.9°F (12.1°C). The average maximum is 63°F (17.2°C) while the average minimum is 45°F (7.2°C).

    Destructive storms are infrequent in the Portland area. Surface winds seldom exceed gale force. Thunderstorms are infrequent, occurring, on average, only seven days each year. Tornadoes with the funnel cloud reaching the ground are rare and there are rare occurrences of heavy rain even though winter rains may persist for days at a time. Ice forms occasionally, but it is seldom heavy enough to affect navigation seriously, although navigation by small craft may be difficult.

    Weather Alerts
    Frost Advisory - 11:14am Thu Oct 29 2026

    ...FROST ADVISORY IN EFFECT FROM MIDNIGHT FRIDAY NIGHT TO 9 AM PDT SATURDAY...

    WHAT: Temperatures of 36 degrees or lower will result in frost
    formation.

    WHERE: Portions of northwest and west central Oregon and southwest
    Washington.

    WHEN: From midnight Friday Night to 9 AM PDT Saturday.

    IMPACTS: Frost could harm sensitive outdoor vegetation. Sensitive
    outdoor plants may be killed if left uncovered.

    ADDITIONAL DETAILS: Frost and freeze headlines are only issued
    through the growing season of April 1 through October 31.
    Therefore, frost or freeze headlines will not be issued beginning
    November 1, even though similar low temperatures are possible.
    Additionally, frost and freeze headlines will no longer be issued
    this growing season for the Upper Hood River Valley, southern
    Willamette Valley, south Washington Cascade Foothills, and north
    Oregon Coast Range as these locations have already experienced a
    hard freeze earlier in October.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    Take steps now to protect tender outdoor plants from the cold.
    Consider temporarily moving outdoor potted plants indoors if they are
    sensitive to cold temperatures.

    Consider temporarily covering sensitive plants with a lightweight
    cotton fabric (i.e., bedsheets, thin blankets), as this will help
    retain heat and provide frost protection for your plants.
