- Reference evapotranspiration
- 28 mm
- Crop requirement
- 19.6 mm
- Forecast rain
- 0.1 mm
Calculation: reference evapotranspiration multiplied by the crop coefficient 0.7, minus rain. Soil reserve and network efficiency are not taken into account.

Citrus farming weather in Cap Bon
The 20,000 hectares of Cap Bon citrus, led by the Maltaise orange, rest on a frost-sensitive fruit: at 0 °C ripe pulp is already affected, and the Maltaise is picked precisely from December to February. At the other end of the year, flowering in March-April and the physiological drop in May-June call for a steady water supply drawn from an aquifer already exposed to seawater intrusion. This page tracks frost, water and spraying windows for Nabeul, Grombalia and Menzel Temime.
Frequently asked questions
- At what temperature does citrus freeze?
- Ripe fruit is affected from 0 °C and damage becomes severe below -2 °C, especially on clear, windless nights when ground-level temperature falls below the sheltered reading. This page flags the risk three steps before that threshold.
- When should Cap Bon citrus be irrigated?
- Needs peak from fruit set through fruit growth, May to September. The water balance on this page compares evapotranspiration adjusted by a crop coefficient of 0.70 with the last seven days of rain, and gives the deficit in mm and in m³ per hectare.
- What conditions suit spraying in a citrus orchard?
- Wind between 3 and 19 km/h, no rain within the following six hours and a Delta T between 2 and 8. The hourly window on this page marks those slots over 48 hours for the Cap Bon area.
