Be prepared for the heat this Memorial Day weekend

Weather Blog

PORTLAND, Ore. (KOIN) — A big warm up is happening this Memorial Day weekend! Temperatures today starts in the upper 40’s. By the afternoon valley temps peak in the upper 70’s to low 80’s. Expect the low to mid 80’s by Sunday.

Will we top 90°? We’ll get close on Memorial Day but most inland pockets of the Willamette Valley remain in the upper 80’s. Tuesday will most likely be our first 90° day for Portland this year.

Be prepared for cold river temperatures this holiday weekend. Remember your life jacket, sunscreen, sunglasses, and keep drinking your water.
