About Soil Temps

SoilTemps.com answers one question well: what is the soil temperature where you live, and what should you do about it? The site serves measured readings from 380+ federal monitoring stations for 2,200+ US cities, with planting windows, pre-emergent timing, and a full lawn care schedule keyed to the thresholds university turfgrass research actually uses.

Why It Exists

The federal SCAN and USCRN networks publish excellent soil data in formats built for researchers, not homeowners. Soil Temps is the consumer frontend for that public data: free, no signup, no paywall, updated daily. Timing recommendations are compiled from university extension research and cited back to the source programs throughout the guides.

What It Is Not

• Not affiliated with USDA or NOAA. The underlying observations are public-domain federal data; the presentation and recommendations are ours.
• Not a weather-model wrapper. Primary readings are measured by in-ground sensors; modeled estimates appear only as a labeled fallback. The methodology page explains the difference.
• Not agronomic advice for commercial operations. The site is built for homeowners; growers should consult their state extension.

Some product links in guides are affiliate links, disclosed on each page where they appear. Affiliate relationships never influence the timing recommendations, which come from the data and the cited research.
