Enhanced Sneaker Wave Threat Sunday 10/11/2026.

Daytime Highs

There is an enhanced threat of sneaker waves Sunday October 11th, 2026. Waves can run up significantly farther on a beach than normal & surprise beachgoers. Sneaker waves can lift or roll large, heavy logs which can lead to serious injury or death. Keep off rocks, logs, and jetties near waterline on beaches. Use caution on beaches, never turn your back on the ocean.

High temperature forecast for Thursday October 8th through Monday October 12th, 2026. Here is a table that shows the high temperature forecast for each day for select cities across northwest Oregon and southwest Washington. Temperatures will be the warmest today with a noticeable cooling trend starting Friday and continuing through at least the weekend. Daytime highs will be in the 60s to 70s across the region with some areas likely warming into the low 80s today. Friday and through the start of next week, daytime highs are forecasted to be 10-20 degrees cooler, with highs in the 50s and 60s. The cause of this pattern shift is an incoming low pressure system from western Canada. This low will bring increasing cloud cover, light/very light rain over the weekend followed by fog and possible frost development in rural areas and the Hood River Valley as overnight lows fall into the 30s and 40s.
