Hourly Pressure Trends
Track the barometric pressure in Shoreline hour by hour across the next 6 hourly readings.
Shoreline, Washington, has a weather pattern shaped by Pacific storms. In fall and winter, low-pressure systems often move inland, bringing clouds, wind, and steady rain. Pressure usually rises after fronts pass, and showers ease. In summer, stronger high pressure often brings longer dry spells.
Nearby Puget Sound softens temperature swings, so cold snaps and hot spells are usually less extreme than inland. Moist Pacific air reaches the area, while the Olympic Mountains can reduce some incoming rain. Local hills and the sound can make cloud and shower amounts vary.
Winter is generally the wettest season, with occasional brief snow when colder air moves south. Spring stays changeable, shifting from showers to brighter breaks. Summer is usually the driest stretch, with mild evenings. In autumn, rain and windy fronts return as Pacific low pressure becomes more frequent.
