Pollen forecast Valjevo

Valjevo lies in the Kolubara basin on the Kolubara river, at the foot of the Valjevo mountains — Povlen, Maljen, and Suvobor, with Divčibare the best-known upland destination above the town. The basin is enclosed and prone to temperature inversions, which trap pollution in winter and, during the season, can hold pollen lower over the town than one might expect.

Main allergens and season

• Late winter and early spring (February–March): alder along the Kolubara, the Gradac, and the Jablanica — common in these valleys, opening the season among the earliest in western Serbia.
• Spring (April–May): birch, which grows naturally in this area on clearings and forest edges in the hills as well as being planted in town; it is the clinically most important woody allergen here.
• Late spring and summer (May–July): grasses from the meadows and pastures of the basin and the mountain clearings; in the hills the season starts later and lasts longer.
• Late summer (August–September): ragweed at moderate concentrations along the Kolubara, the roads, and on neglected plots; mugwort leads the way from July.

Valjevo 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.
