In Monaco, the Saharan dust episode led the government to issue recommendations: what should be done if another episode of pollution occurs?

During the episode of fine particulate matter pollution on Friday 28 August 2026, the Prince’s government issued a list of health and transport recommendations. What should you do if such an event occurs again in the future?

“Air quality has returned to normal. The pollution episode caused by Saharan sand dust has ended.” On Saturday 29 August, via its social media channels, the Prince’s government sought to reassure the public following the alert issued the previous day at around 3 pm.

On Friday 28 August, based on air quality data measured by the Environment Department at its five monitoring stations*, the Monegasque government warned that the information threshold for fine particulate matter (PM10) pollution – 80 µg/m³ – could potentially be reached.

This was due to a persistent Saharan dust episode, coupled with weather conditions that were unfavourable to the dispersion of pollutants.

The Monegasque government had issued a number of recommendations, which are worth knowing (and following) should such a phenomenon occur again in the future.
