I don't think you'd have any issues in OR or WA with materially impactful COVID restrictions. However I would be mindful of stops at Native America communities and Neah Bay, WA is a key one. The Makah tribe https://makah.com/
runs the fuel dock and it's one of those places where it's the last place for fuel before jumping out in the Pacific. Currently it's closed to non-tribal folks however I believe you are still allowed to anchor in the bay.
You can get fuel in Port Angeles, WA which is 54 miles east of Neah Bay. Your logical hop would be from Neah Bay, WA to Westport, WA. It's about 155 miles from Port Angeles to Westport so you could easily make it on a fill up from Port Angeles to Neah Bay then onto Westport.
We visited a number of Oregon coastal towns in early April. The southern coast had tighter restrictions than the central coast because they were dealing with an outbreak. So restaurants were take out only at the time but pretty much everything was open. By the time you'd be down here I can't imagine COVID impacting your plans much.
