Soil temperature at 6cm in Sheffield, England is currently 15.5°C, and falling about 2.7°C over the next 11 days. That depth matters because it is where grass seed sits and where roots start working, and it lags air temperature by days — which is why a warm afternoon here tells you very little on its own.
