Weather in July

July is usually the hottest and sunniest month of the year in Oregon. The average high temperatures across the state are between 64°F (17.8°C) to 94°F (34.4°C) with many cities in the range of 85°F (29.4°C) to 90°F (32.2°C). Ontario, on the eastern border, registers many days above 100°F (37.8°C). The conditions are scorching hot in the High desert region, where it is better to spend afternoons in the shade. The days are sunny and bright everywhere, and the skies are blue and clear. Solar radiation is at its peak during July.
Humidity decreases when moving from the coast to the east. Peak summer is the height of the tourist season with a multitude of outdoor activities like camping, fishing, swimming, biking, and trailing. Light summer clothing is suitable on the plains during the day, while a light sweater makes the nights comfortable in the highlands. July is dry in the majority of Oregon, but thunderstorms with lightning occur periodically.
