Farming weather
Soil temperatures today read surface 23 °C, 6 cm 26 °C, 18 cm 28 °C, 54 cm 23.5 °C. Soil moisture sits at 0-1 cm at 0.17 m³/m³, 3-9 cm at 0.2 m³/m³, 27-81 cm at 0.29 m³/m³. For wheat, the root-zone reading is within the ideal 0.2-0.35 m³/m³ band. Reference evapotranspiration totals 34 mm against only 1 mm of expected rain — a 33 mm deficit, so irrigation will be needed this week. A suitable spraying window opens around 07:00 on 2026-06-21, with winds at or below 15 km/h and no rain expected. Heat stress is likely for wheat with highs reaching 33 °C (threshold 32 °C). Projected growing degree days over the next week: wheat 129, maize 90.
