How Often Does it Rain on Halloween in Kitsap County?

I love Halloween. I don’t know why…I just do. And my co-workers and I were discussing how for the past 10 years or so it seems we consistently manage a dry Halloween here. So, I took it upon myself to do some research and find out how many Halloweens since 1999 featured rain. Here’s what I found:

  • 1999: 0.09”
  • 2000: 0.00”
  • 2001: 0.44”
  • 2002: 0.00”
  • 2003: 0.00”
  • 2004: 0.00”
  • 2005: 0.73”
  • 2006: 0.00”
  • 2007: 0.00”
  • 2008: 0.45” (Dry with partially clear skies by trick-or-treating time)

So it turns out 6 Halloweens in the past 10 years have been bone dry (Ha! Pun!) with 2008 featuring dry conditions by the time most went out with their costumes and pillow cases. So techincally we can say 7/10 Halloweens here have been ideal. Hmmm…I’ll take a 70%! And there’s something I noticed…after every “wet” Halloween, it seems many dry Halloweens follow. There has never been two consecutive wet Halloweens in 10 years!

So I would like to place our odds at “pretty darn good” for your outdoor activities, but long range models have been toying with the idea of a very wet and chilly Halloween. In fact, most of next week looks wet, windy and cold with some mountain snow but poor outdoor conditions in the lowlands.

Of course Halloween is a week and a half away and weather data has plenty of time to change, but we’ll see. I’ll do a long range forecast on Friday or Saturday and by then we should have a pretty good idea of what to expect.

Have a fantastic day everyone! The clouds and fog don’t seem to want to budge, but it will stay dry…until tomorrow 😉
