Soil Moisture in Washington
Soil moisture across Washington, interpolated from the latest readings at each station and refreshed daily. Brown is drier than normal, teal is wetter than normal.
Across 5 monitoring stations in Washington, 1 is wetter than normal, 1 is about normal, and 3 are drier than normal. Last updated October 17, 2026. Each station is compared against its own moisture history for this date, not against other stations, so wetter or drier than normal means the same thing at every station.
How This Is Measured
Every reading here is measured by an in-ground sensor at USDA SCAN (Soil Climate Analysis Network) and NOAA USCRN (US Climate Reference Network) stations, at or near the 2-inch root-zone depth, not modeled. A raw moisture percentage is not comparable between two soils, so each station is compared against its own history for the date. That comparison, wetter or drier than this station normally is, is the honest signal. These stations belong to the 326 active USDA and NOAA in-ground monitoring stations Soil Temps reads; only those with a moisture sensor and at least two years of their own history are compared here.
Stations Measuring Soil Moisture in Washington (5)
| Station | Depth | Moisture | vs. Normal | Last Reading |
|---|---|---|---|---|
| Cook Farm Field D USDA SCAN | 2" | 11% | Much drier than normal | Oct 17, 2026 |
| Lind #1 USDA SCAN | 2" | 0% | Much drier than normal | Oct 17, 2026 |
| Darrington 21 NNE NOAA USCRN | 2" | 18% | Drier than normal | Oct 17, 2026 |
| Quinault 4 NE NOAA USCRN | 2" | 28% | Wetter than normal | Oct 17, 2026 |
| Spokane 17 SSW NOAA USCRN | 2" | 8% | Normal for this time of year | Oct 17, 2026 |
Moisture is the volumetric water content at the sensor. It is not comparable between soils, which is why the “vs. normal” comparison against each station’s own history is the reading to trust. No comparison yet means that station does not yet have enough of its own history for a confident comparison.

Soil Moisture FAQ for Washington
How wet is the soil in Washington right now?
Across 5 monitoring stations in Washington, 1 is wetter than normal, 1 is about normal, and 3 are drier than normal. Last updated October 17, 2026. Each station is compared against its own moisture history for the date, so the reading means the same thing everywhere.
Where does Washington soil moisture data come from?
Every value is measured by an in-ground sensor, not estimated from a weather model. Readings come from the USDA SCAN network and NOAA USCRN stations, at or near the 2-inch root-zone depth (some stations report at the nearest available depth), and are refreshed daily.
What does wetter or drier than normal mean?
For each station, the current reading is compared against that station's own readings around this date across several years, after leaving out frozen-soil days. A raw moisture percentage is not comparable between two different soils, so the comparison against a station's own history is what makes the reading meaningful.
