Umán farming weather

Soil, irrigation, spray-window and crop-stress guidance for Yucatán, Mexico.

Field summary

Soil temperatures today read surface 25 °C, 6 cm 28 °C, 18 cm 30.2 °C, 54 cm 29.7 °C. Soil moisture sits at 0-1 cm at 0.21 m³/m³, 3-9 cm at 0.21 m³/m³, 27-81 cm at 0.25 m³/m³. For wheat, the root-zone reading is within the ideal 0.2-0.35 m³/m³ band. Reference evapotranspiration totals 39 mm against only 13 mm of expected rain — a 26 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 wheat with highs reaching 36 °C (threshold 32 °C). Heat stress is likely for maize with highs reaching 36 °C (threshold 35 °C). Projected growing degree days over the next week: wheat 178, maize 140.
