North Africa: Heatwave forecast to persist across much of Algeria, Morocco, and Tunisia through at least July 14

Heatwave forecast to persist across Algeria, Morocco, and Tunisia through July 14. Localized transport and utility disruptions possible.


Forecast models indicate that a heatwave will persist across much of Algeria, Morocco, and Tunisia through at least July 14. Daily maximum temperatures of up to 49 C (120 F) are possible across parts of the region in the coming days.

As of July 10, the respective meteorological services have issued the following high-temperature warnings across the affected area:

  • Red heatwave warnings: Parts of central, eastern, and north-central Morocco.
  • Orange heatwave warnings: Across much of northern Algeria, parts of central, northern, southern, and western Morocco, and across northwestern, southern, and southwestern Tunisia.
  • Yellow heatwave warnings: Across much of the rest of the region not under red or orange warnings, with the exception of parts of central, southern, southeastern, and western Algeria and eastern and northeastern Tunisia.

Authorities will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

The extended period of very high temperatures and dry conditions may increase the potential for wildfires throughout the region. The high temperatures may result in drought conditions in the country. Authorities may implement water rationing, restricting water supply when necessary, as well as prohibiting the use of potable water to irrigate green spaces or limiting water withdrawal from wells, springs, or waterways.

Heatwaves pose a health threat to vulnerable groups, such as the elderly, children, pregnant women, and those with respiratory illnesses, due to the increased possibility of heat stroke or heat exhaustion during prolonged exposure to high temperatures. These risks could also extend to relatively healthy individuals during significant heatwave events. In addition to significantly impacting athletes and those who work outdoors, high temperatures can cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to some passengers being hospitalized for dehydration.

Transport and Utilities
Overheated vehicles could prompt traffic disruptions in urban areas where congestion is already a problem. Commercial trucking disruptions might occur, as very high temperatures put more stress on vehicles and make tire blowouts more common. Major flight disruptions are unlikely at regional airports, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads. High temperatures could lead to an increased demand for electricity, which might trigger localized brownouts or blackouts, exacerbating hazardous conditions when air conditioning is no longer possible.


Monitor local media for weather updates and related advisories. Consider remaining indoors in air conditioning when possible, particularly if operating in one of the worst-affected regions. If outdoor activities are necessary, frequently rest in shaded areas; avoid activity during the hottest times of the day. Stay well-hydrated by drinking plenty of fluids. Avoid caffeinated and alcoholic beverages, which are dehydrating. Wear loose-fitting, light-colored clothing. Cotton fabrics are more cooling than synthetics. Promptly seek medical attention if signs of heat exhaustion or heat stroke develop. Charge battery-powered devices in case prolonged electricity outages occur.
