Pressure and weather in Edmonds
Edmonds sits on the eastern shore of Puget Sound, its waterfront and ferry terminal facing west across the water toward the Olympic Mountains, which sit far enough away to only partly shield the town from incoming Pacific weather. Most of Edmonds's pressure activity arrives from the Pacific in the form of a nearly continuous parade of low-pressure systems from fall through spring, some intensifying into atmospheric rivers, long plumes of tropical moisture that can drop the barometer noticeably as they make landfall. The Puget Sound convergence zone, a local quirk where air splitting around the Olympics east of Edmonds reconverges over the sound, can locally enhance rain and wind during an otherwise ordinary frontal passage, adding an extra layer of variability on top of the larger-scale pressure pattern. November through February is the most active stretch, when the jet stream sits directly overhead and storms arrive back to back, sometimes barely giving the pressure time to recover between systems. Summers are a different world entirely, with a persistent offshore ridge keeping the region dry, sunny and comparatively stable for weeks at a time. Spring and fall are transition seasons, with pressure patterns gradually shifting from one extreme to the other.
What this means for you
Edmonds sees its fastest and most frequent pressure swings from November through February, when Pacific storms and atmospheric rivers arrive in quick succession. A barometric pressure forecast can help you anticipate these systems a day or two out, and pairing it with a migraine tracker app can clarify whether it's the pressure drop itself or the accompanying wind and rain driving your weather migraine.
