Weather forecast for the PNW

[jssailem]

I am preparing for my July summer cruise. Been looking forward to this for the past several years.

Here is the Rufus Weather outlook for the first half of July.

Have a great USA Celebration on the 4th. And you sailors north of the 49th Parallel, Happy Canada Day on July 1st.

Monday June 30​

​

Greetings. Lots of Patrons switching ice coffee, ice tea, etc as Summer weather finally grabs hold of the PNW. The hot days early this week are the prelude to very uncomfortable Summer heat coming soon. That said, the upcoming USA holiday wx will be right up there with the best of the best. Curious? Mug up and read on.​

• As stated, today & Tue July 1 look to be the hottest of this pre-holiday week. 90s will be common region wide; almost 90 around the Puget Sound. A few thunderstorms may develop over the east slopes of the Oregon Cascades, as well. Wed-Fri trends a bit cooler, but still notably warm outside. (There is a chance a quick shot of clouds and foothill showers overnight Wed ONLY but limited to north Puget Sound.) Pleasant overnight temps. ​
• 4th of July Weekend: exceptional holiday / camping weather!! One of the best favorable stretches of holiday wx we can hope for in the great PNW. Everyone will enjoy. Temps in the 80s, with a comfortable onshore flow of ‘cool’ air. Temps during local firework presentations are looking comfortable. Oh yeah.​
• Post holiday week, July 7-11 begins the transition to HOT — and a potentially extended period of 90+ temps across the entire PNW, with triple-digit highs probable as July progresses. ​
• Weekend of July 12,13: a short break from the heat is possible, with an onshore breeze picking-up to allow for a decent break from the heat.​
• Week of July 14-18: temperatures ramp back up into the 90s in many locations; triple-digit highs in the eastern basins and southern OR. Willamette Valley may hit 98-101, as well.​

Bottom line: a string of 90 degree plus temps is looking more & more probable during the first half of July 2025. Keep those irrigation pumps running; protect home landscaping, if traveling away for a Summer vacation. NO precipitation is charting in the next 20 days or so (excluding the baby showers noted above Wed night, July 2).​

Yes,
After numerous delays and not taking care of chores when I had the chance(s) earlier, I think I will finally get out of Liberty Bay and up to Port Townsend on Sunday.

And so far, to the best of my knowledge, we do not need to do planning and weather routing around forest fire smoke (yet).

Not that I have heard reported. I updated my radar system this year. I’m hoping it will resolve the challenge of fog and smoke visibility issues.

Just got an update from Rufus. As can be expected Weather is shifting. Plan for some rainfall in the next’s 10 days.


4th of July 2025

Quick update, as models have shifted the outlook for the next 2 weeks, maybe.

• Holiday Weekend: mild temps, with warming each day; showers over eastern basins because of Low moving across SE corner of OR thru ID today only. Sunday will turn rather warm, leading into - - -
• Week of July 7-11: HOT Mon & Tue; cooler on Wed with a Low brushing past NW WA & BC - a Puget Sound shower is possible. Temps begin to bump up again starting Thu the 10th, on into the weekend.
• July 12-13 weekend: high temps range from 80s to mid 90s probable in most locations, excluding coastal zones. Breezy afternoons. Sunday late a damp front may begin to push inland from the NW. This is iffy right now, we’ll monitor.
• Week of July 14-18: indications are for a cooler week, in general, than typical July conditions; not bad for growers & small fruit harvest. It will be mild, with warmest days mid-week.
• July 19-20 weekend: turning hot again.

Forecast changes are to be expected, so keep your Mug handy & enjoy the 4th!
