(Cannon Beach, Oregon) - After a few days of rain last week, the Oregon and Washington coast are again sunny for awhile – at least a week. According to the National Weather Service (NWS) offices in Portland, Medford and Seattle, expect to see fairly warm temps and mostly sunny skies along the coastlines of Washington and Oregon. (Above: Pacific City at night. While not actually the glowing waves effect, the look is not too dissimilar. See below for actualy glowing waves)

This may again greatly increase your chances of seeing the glowing waves at night as well as the glowing sand phenomena. Last week’s rain killed off all the nearshore bioluminescent phytoplankton, but sunny, clear conditions allow that to return. On top of that, Seaside Aquarium is reporting a heavy diatom bloom in the area, the result of some rain and then a resurgence of sun. If one kind of phytoplankton is blooming in great numbers, it’s quite possible the glowing kind is as well. See Astounding Glowing Waves (and Sand) on Oregon Coast Right Now 

Your chances of seeing this stunning oddity are much better now – a rarity that’s been happening often this summer. It is not guaranteed, however.

On the central Washington coast, conditions appear to be a little sunnier than Oregon beaches for the week. Predictions for Monday through Saturday are for highs in the 60s and low 70s, with patchy fog in the mornings on many days that burn away later.

On the upper half of the Oregon coast (including Cannon Beach, Pacific City, Yachats, etc.), afternoon highs are mostly 65 to 70 for much of the week, with partly cloudy skies. Wednesday looks to have the sunniest conditions at this time.

There’s more sun the farther south you go, as you get closer to Coos Bay. The southern end of the Oregon coast will get higher temps, however, especially nearing next weekend when the forecast calls for about 80s degrees in areas like Brookings.

Throughout the week, most of the Oregon and Washington coastlines remain in a fairly similar pattern.

“A weak upper trough lingers over the area through Wednesday night continuing the possibility of coastal marine clouds moving inland Thursday morning,” the NWS said. “Any clouds will quickly clear late Thursday morning as a weak upper ridge moves over the area. The winds will be light, but lose the onshore component such that the temperatures will be slightly warmer on Thursday afternoon with interior areas peaking in the mid to upper 80s and coastal areas in the lower 70s.”

There is the possibility of thunderstorms farther south which may make it into the southern coast later in the week. An unusual pattern that’s interacting with all this are the wildfires from California, which is causing haze and hazardous smoke in some areas of southern Oregon. The NWS said this haze may inhibit the formation of thunderstorms, however.

TRAVEL ADVISORY: Avoid the north Oregon coast for now as it is overwhelmed and you may not find a parking spot or proper facilities. -------- See Oregon Coast Weather - Washington Coast Weather
