Pollen and allergies — Mostar
Mostar, in Herzegovina on the Neretva river, has a Mediterranean climate with hot, dry summers and mild winters. Its sheltered position in the Neretva valley and proximity to the Adriatic make it one of the warmest cities in Bosnia and Herzegovina, and subtropical vegetation — olive trees, cypresses and figs — marks the surroundings.
Main allergens and season
- Winter and early spring (February–April): cypresses and alder along the Neretva, and in spring the flowering of olive trees — a key local allergen in Mostar.
- Late spring and summer (May–July): grasses from the surrounding rocky pastures.
- Late summer (August–September): mugwort, while ragweed is present but less dominant than in the continental cities.
Mostar does not have its own measuring station on this service, so the displayed forecast is based on the European CAMS model (via Open-Meteo) — the values are modeled, not measured, but a useful guide for planning outdoor activities.
