Date palm farming weather
Tunisia's Deglet Nour crop is decided in a few weeks of October and November: 20 mm of rain on ripe bunches is enough to split the fruit and start rot, while the oasis spends the rest of the year under an almost rainless climate. Before that, hand pollination in March and April needs calm days, and summer demands 1,500 to 2,000 m³ of water per hectare per month from an aquifer already under pressure. This page follows those three moments for Tozeur, Kebili and Gabes.
Frequently asked questions
- How much rain threatens the date harvest?
- From 8 mm in a day, ripe Deglet Nour start absorbing water and splitting; above 20 mm the risk of rot becomes high. This page flags those thresholds over the coming seven days during the harvest period.
- What conditions suit date palm pollination?
- Hand pollination in March and April needs a dry, low-wind day: above 25 to 30 km/h the pollen is carried away before it settles. The wind forecast on this page helps pick the day.
- How much water does a palm grove use in summer?
- The water balance on this page estimates the need from reference evapotranspiration and a crop coefficient of 0.90, converted into m³ per hectare. It is an order of magnitude for adjusting an irrigation turn, not an irrigation instruction: soil reserve and network efficiency are not part of the calculation.
