Pressure and weather in Sammamish

Autumn and winter Pacific lows bring repeated pressure falls and recoveries to Sammamish. Surrounding terrain changes rainfall from place to place, while summer often brings longer dry intervals under a stronger northeastern Pacific high.

What this means for you

Keep notes on a wet plateau commute separately from a drier lakeside break. A barometric pressure forecast represents the broader system, so the rain you encounter is an additional observation rather than a substitute for the chart.
