About those rainy days: It takes only one one-hundredth of an inch (0.254 mm) of precipitation for a day to move into the category of "rainy" (not sunny), whether the precipitation falls as rain, snow, sleet or hail.

This is an average, of course. While highs DO hover around 70F on a lot of summer days, we do get days into the 80's F (26.7 C).

At the same time, summertime 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 Sequim tend to make it a habit to check weather forecasts regularly.

Sequim Weather Disclaimer

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 Sequim weather is that there are multiple weather services in the United States, and their statistics rarely match, not even in their past records!

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...!
