Port Townsend Weather Info and Stats

Sunny Days vs. Rainy Days: In Port Townsend the sunny days (156 days per year) outnumber the rainy days (138 days per year), which is a plus. This is still the Pacific Northwest however; the national average for sunny days is actually 205 days. 

About those rainy days: It takes only one one-hundredth of an inch (0.254 mm) of precipitation for the day to move into the category of "rainy" (not sunny), whether the precipitation falls as rain, snow, sleet or hail. We've enjoyed some very lovely "rainy" days around here, just sayin'! When that fraction of an inch falls between the hours of 1 a.m. and 4 a.m., our days are delightful.

Port Townsend Weather: Average Temperatures 

Summer Highs: July and August are the warmest months in Port Townsend. The average high temp in July is around 70F (21.1C), and August's average high is 71F (21.67C).

These are averages, of course. While highs DO hover around 70F on a lot of summer days, we do get days into the 80'sF. The likelihood of temperatures soaring into the 90's (32.2+C)...well, we might get 1-3 days per year, maybe, with temps that high. At the same time, highs can easily dip into the 60's (C).

This is why it is smart to bring a good sweater or light jacket even if you're visiting in July. It is also why the denizens of Port Townsend tend to make it a habit to check weather forecasts regularly. 

Winter Lows: December and January average low temps are 38F (3.33C), however they tend to fluctuate between just above freezing (32F - 0C), and upward into the low 40's (4.44C).

Port Townsend Weather Disclaimer

Note: I'd like to believe that our weathermen can come to a reliable forecast at least a few minutes before I have to check the "weather rock" in my front yard. (You know - if the rock is wet, it's raining, if it's rolling it's windy, if it's white it's snowing....)

But, what I discovered after researching Port Townsend weather is that there are multiple weather services in the United States, and in no way do their statistics perfectly match one with another, not even in their past records!

But at least each weather service bats within the ballpark, so to speak. So, if you notice that our statistics aren't exactly the same as someone else's statistics, I won't be surprised. A whole lot depends upon where those stats come from. Nevertheless, I hope that your set and my set of stats are at  least close...!
