Water in
Observed and incoming rain
Recent NOAA and NWS observations are reconciled before the decision. Forecast probability is never turned into an invented rainfall amount.

Should I water my garden today?
Enter a city or ZIP. The tool replays observed rain and recent drying, checks what is coming next, and gives you a plain watering decision instead of another weather dashboard.

What goes into the call
Water out
Recent drying and today's demand
Observed temperatures drive the recent water-loss ledger. NWS reference evapotranspiration is preferred for today's atmospheric demand.
Water storage
Soil and root-zone context
USDA mapped soil and crop rooting depth estimate storage. The tool carries uncertainty as a range rather than pretending it measured your soil moisture.
This is a weather-and-soil decision model, not a soil-moisture sensor. If you watered recently or have a rain-gauge reading, add it under “Adjust this result for my garden.”
