Weather and climate
Will the sky be clear? No one can know yet. But climate statistics show that early August mornings in Tunisia are among the sunniest of the year.
As of 25 October 2026, no weather forecast exists for 2 August 2027: reliable forecasts are only possible about one to two weeks in advance. This page presents climate statistics, not forecasts.
1. Climate statistics (historical data)
The table below summarises the total cloud cover and the temperature at 10:00 Tunisian time (09:00 UTC), the time of the eclipse, for each day from 26 July to 9 August over 25 years (2000–2024), i.e. 375 values per site.
| Site | Mean cloud cover | Clear sky (≤ 10 %) | Cloudy (≥ 50 %) | Mean temperature |
|---|---|---|---|---|
| Houmt Souk (Djerba) | 4.1% | 89% | 2% | 31.4 °C |
| Gafsa | 4.2% | 90% | 2% | 31.9 °C |
| Tozeur | 4.5% | 91% | 4% | 33.6 °C |
| Sfax | 4.8% | 89% | 3% | 29.9 °C |
| Gabès | 5.0% | 87% | 2% | 30.4 °C |
| Sidi Bouzid | 5.1% | 89% | 3% | 31.8 °C |
| El Jem | 5.2% | 90% | 4% | 30.9 °C |
| Mahdia | 5.3% | 88% | 4% | 31.1 °C |
| Sousse Partial eclipse | 5.9% | 88% | 4% | 30.6 °C |
| Kairouan | 6.5% | 85% | 5% | 31.9 °C |
| Sbeitla | 6.6% | 86% | 6% | 32.1 °C |
| Tunis Partial eclipse | 7.8% | 83% | 5% | 29.8 °C |
What these figures mean
- Early August mornings are usually clear everywhere in the path: clear-sky situations (≤ 10 % cloud cover) represent the large majority of days.
- Differences between sites are small. The northern edge of the path and the Sahel coast are slightly cloudier than the south and the inland steppe, consistent with the satellite climatology published by the meteorologist Jay Anderson (Eclipsophile), which finds the lowest morning cloudiness around Sfax and to the south.
- The main atmospheric risk is not cloud but dust and haze carried by southerly winds (sirocco), which can veil the sky and reduce contrast.
- Heat: temperatures at 10:00 are already around 30 °C or more, especially inland. Plan shade and water.
2. Forecasts available a few days before
- From about ten days before the eclipse, global models (for example those of ECMWF) give the first indications of the general weather pattern.
- In the last three days, the forecasts of the National Institute of Meteorology of Tunisia (INM) and dust forecasts (WMO Barcelona Dust Regional Center, up to 72 hours ahead) become the most useful references.
- On the eve and the morning of the eclipse, satellite images help choose between nearby sites.
3. What cannot be known yet
Any "forecast" for 2 August 2027 published today is not scientifically meaningful. This page will be updated as soon as usable forecasts exist.
