What's under the hood

The weather and terrain behind each estimate.

7-day rain history

Rain from earlier in the week can still leave the ground wet. Loam considers the full week of rainfall.

Soil type awareness

Sandy soil drains faster than clay. Soil survey data helps estimate how long the ground holds water.

Slope & drainage

Slope affects drainage. Loam uses local terrain data to account for water running off hills or collecting on flat ground.

Evaporation model

Sun, wind, temperature, and humidity affect drying. Loam updates hourly and estimates how conditions will change.
