Understanding farming weather in Tunisia
Tunisian agriculture turns on a small number of critical moments: the November sowing window in the North-West, olive flowering in April, grain filling in May, the date harvest in October. A temperature forecast alone does not anticipate them: what matters is the combination of wind, humidity and evapotranspiration.
This section turns those combinations into directly usable indicators: an hourly window for applying products, a water balance in millimetres and cubic metres per hectare, and alerts on the phenomena that actually cause damage in Tunisia, starting with the sirocco and late-winter frosts.
Frequently asked questions
- What is Delta T and why check it before spraying?
- Delta T is the gap between air temperature and wet-bulb temperature. Below 2, droplets stay suspended and drift off the field; above 10, they evaporate before reaching the leaf. The useful range is 2 to 8, which in Tunisia often means early morning.
- How is the water requirement calculated?
- From the FAO-56 reference evapotranspiration supplied by the model, multiplied by a crop coefficient, minus forecast rain. The result is converted into cubic metres per hectare, one millimetre over one hectare being ten cubic metres. It is an order of magnitude, not an irrigation instruction.
- What is the sirocco and why a separate alert?
- The sirocco is the Saharan southerly wind: hot, dry and often strong. Equivalent heat without a southerly flow does not do the same damage; it is wind desiccation that burns olive flowering and scorches grain. The alert therefore fires only when heat, dry air and a southerly wind come together.
Indicators computed from Open-Meteo forecasts. They help pick a moment to intervene; they replace neither an official agricultural advisory nor a technician's judgement.
