Farming weather
Soil temperatures today read surface 13.9 °C, 6 cm 12.4 °C, 18 cm 13.6 °C, 54 cm 15.6 °C. Soil moisture sits at 0-1 cm at 0.39 m³/m³, 3-9 cm at 0.39 m³/m³, 27-81 cm at 0.34 m³/m³. For wheat, the root-zone reading is above the ideal 0.2-0.35 m³/m³ band. Forecast rain (28 mm) roughly covers crop water demand (ET0 12 mm), so irrigation can likely be paused. A suitable spraying window opens around 08:00 on 2026-06-21, with winds at or below 15 km/h and no rain expected. Frost risk for wheat: lows dip to 2 °C, under the 2 °C damage threshold. Frost risk for maize: lows dip to 2 °C, under the 4 °C damage threshold. Projected growing degree days over the next week: wheat 41, maize 7.
