As said above the rains are unpredictable. It could be extremely hot or rain the whole time. But the rain is not cold in July. We usually have a 50/50 % chance of rain on July 4th but it usually
clears up after that.
Do bring rain gear
If you don't have a bimini
, bring a tarp and some line/poles to rig a cover.
For the mornings you'll want some type of heater to break the chill, even if the weather is good.
Bring some warm blankets and your jamies for sleeping.
coverage is through out the Puget Sound
The water temperature averages around 56º in the Sound but can warm up a bit in enclosed shallows.
Do bring a tide chart
and pay attention to it! Some narrows can get so swift to create whirl pools. But powerboats usually pass right over the top w/o any trouble.
The winds can come either out of the North or South and may change during the day. Sucia is fairly
protected from both. The waters within the Islands stay fairly calm but outside of the Islands it can get choppy. Just listen to the the WX stations before heading outside of the islands. And do bring a chart book w/ an index
so you know what area they are talking about.
I have run into to some bad waters between Anacortes and the Islands but the thing to remember with chop is to go slow but do keep moving.
