St. Johns combines small-town charm with waterfront weather. Cool breezes from the Willamette and Columbia meet here, dropping temperatures quickly after sunset. In winter, fog gathers near Cathedral Park and lingers through morning, giving homes that signature Portland chill. Summer days bring welcome warmth—but even then, evenings cool down fast enough to keep everyone reaching for an extra layer.

"Working AM/PM Heating and Cooling was smooth from start to finish. Our heat pump was completely not working and they were able to send someone out the same day I called. Our technician Austin was friendly, communicative, and got the job done quickly."
