Whidbey is a bigger island, but it should be similar. We've been having a pretty exceptional summer this year. It's been warm and dry... (unlike the past 2 years, when I never even got tan lines, because it wasn't ever warm enough to take the knee and arm warmers off....) I do have to warn you, even though it was shorts weather at my house yesterday. It was very windy and a bit nippy out on the island. I was fine cycling in my shorts and short sleeves, but on my way home I could have used long pants and a jacket outside of the car, so pack some chilly weather gear too (and it nearly always cools off considerably at night around here).
