Sequim boasts 300 days of sunshine a year, thanks to its prime location inside the Olympic Rain Shadow. Although I'm dubious Sequim gets 300 full sunshine days -- maybe if they count a peek of sun, but 300 days is more than Phoenix -- I do concur that Sequim gets a whole lot more sunshine than their Seattle counterparts.
And now, thanks to David Britton, you can find out just how much sun by a click of the button.
Britton runs OlympicRainShadow.com, a site dedicated to highlighting the weather advantages the Olympic Peninsula has over Seattle. He has this site that shows real-time sunshine information between Seattle, Port Townsend, Sequim and Port Angeles:
(Yes, I realize choosing a blazingly sunny day across the region might not have been the best time to take a screen grab. Oops.)
The solar radiation data is sourced on the fly and updates at least once a minute.
Britton says the readings are polled from three Davis Weather Instrument sensors in Port Townsend, Port Angeles and Sequim, and from the sun sensor atop the University of Washington's Atmospheric Sciences Building in Seattle.
He says the code was quite complex, needing to correct data for time of year for his icon classifications as a sunny winter day will have less output than a partly sunny summer day.
But next time you're in the clouds and rain in Seattle and feel like you gotta gave some sun but the mountain passes are just too crazy, check out Britton's site -- sun might just be a ferry ride away.
