Farming weather
Soil temperatures today read surface 31 °C, 6 cm 35.2 °C, 18 cm 39.3 °C, 54 cm 36.1 °C. Soil moisture sits at 0-1 cm at 0.03 m³/m³, 3-9 cm at 0.08 m³/m³, 27-81 cm at 0.13 m³/m³. For maize, the root-zone reading is below the ideal 0.2-0.35 m³/m³ band. Reference evapotranspiration totals 86 mm against only 5 mm of expected rain — a 81 mm deficit, so irrigation will be needed this week. A suitable spraying window opens around 06:00 on 2026-06-21, with winds at or below 15 km/h and no rain expected. Heat stress is likely for maize with highs reaching 44 °C (threshold 35 °C). Heat stress is likely for wheat with highs reaching 44 °C (threshold 32 °C). Projected growing degree days over the next week: maize 165, wheat 204.
