Roseburg Could See Its Last 90-Degree Day Wednesday

ROSEBURG, Ore. - Sept 9. 2026 - Wednesday could be Roseburg’s final 90-degree day of the year as a significant cooling trend approaches Southern Oregon.

The National Weather Service forecast calls for sunny skies and a high near 93 degrees Wednesday. Temperatures are then expected to fall steadily, with a high near 85 Thursday and 76 Friday.

A low-pressure system will bring a more dramatic change Saturday. Rain is likely before 11 a.m., followed by showers and a possible thunderstorm during the afternoon. Saturday’s high is forecast to reach only 65 degrees, with a 70% chance of precipitation. Rainfall amounts between one-tenth and one-quarter of an inch are possible, with higher amounts in thunderstorms.

Dry weather is expected to return Sunday, but temperatures will remain mild. Roseburg is forecast to reach 72 Sunday, followed by highs near 76 Monday and Tuesday next week.

Although another stretch of hot weather later this month cannot be ruled out, the current forecast shows no additional 90-degree days. If that outlook holds, Wednesday could mark Roseburg’s final day in the 90s this year.
