The vast majority of my driving these days is 1.5 mi to/from the bus transit center, which means the temperature needle rarely moves past cold. This weekend when I drove for 45 min on the highway, I noticed my Autometer boost gauge was getting fogged up with moisture. Since the line to the gauge is basically a closed system from the engine, I assume that means there is (or was) a lot of extra moisture in the engine/oil/other, which has accumulated from all the cold driving I typically do.

Is this to be expected given the driving conditions/climate or a sign to come of problems ahead?

The problem is actually more than likely related to the atmosphere in the car. The line coming from the engine is sealed. Knowing Seattle weather....cold and damp/wet, you'll get a pretty humid environment in the car, especially if you don't have time for things to heat up and evaporate some of the moisture.

I've experienced this in Houston. Turning on the parking lights so the light in the gauge comes on will help heat up the gauge and evaporate the condensation. You may just need to go for a longer drive with the heat/AC on to help dry out the interior of the car.
