The weather in Coos Bay brings rapid changes in barometric pressure, with highs and lows often following each other closely. This is because the area is prone to storms and high winds that shift the air pressure quickly.
The bay's low elevation near the ocean, surrounded by mountains, traps and channels air masses, making pressure changes more dramatic. The varied landscape also blocks or redirects wind patterns, adding to pressure fluctuations.
In the winter, pressure is generally lower, bringing more rain and wind. In the summer, pressure is higher, leading to clearer skies and warmer temperatures. Spring and fall bring more variability in pressure and weather.
Coos Bay has a marine west coast climate, which means it has mild temperatures and high humidity year-round, leading to frequent pressure changes and unpredictable weather.
