Nice and the Alpes-Maritimes are on red alert for pollen. The National Aerobiological Monitoring Network (RNSA) warns of a high concentration of pollen in the air. Allergic individuals should take precautions.
Winter is not over yet, but allergies are already resurfacing. On Sunday, February 16, 2025, the RNSA announced a high risk of pollen allergy in the Alpes-Maritimes. The main cause: Cupressaceae, a family of plants that includes cypress and junipers.
The mimosa, in full bloom, is also an aggravating factor. Other pollens, such as those from ash, alder, and hazel, are also present in moderate quantities. The monitoring organization advises sensitive individuals to be extra cautious.
Favorable conditions for dispersion
Temperatures in Nice are above seasonal norms, with minimums 3°C higher. Sunshine and the absence of precipitation promote the dispersion of pollen.
To limit allergic reactions, several precautions are recommended:
- Regularly check the pollen alert map.
- Rinse your hair in the evening to avoid depositing pollen on the pillow.
- Ventilate your home early in the morning or late in the evening.
- Avoid drying clothes outdoors.
- Keep car windows closed.
- Wear a mask outdoors.
- Limit outdoor sporting activities.
Urban pollution can also worsen allergic symptoms. AtmoSud, the air quality observatory in the South region, reminds us that fine particles and pollen form an irritating mix for the respiratory tract.
The rest of the country is on yellow alert, with a moderate allergy risk. In Nice, the coming days promise to be challenging for individuals sensitive to pollen.
