Pollen concentration
Za ovaj izvor trenutno je dostupna samo jedna objavljena vrijednost, pa linijski trend ne bi bio pouzdan. Prikazujemo najrelevantnije trenutačne koncentracije.
Climate and vegetation
A Mediterranean climate with hot, dry summers and mild, wet winters. The vegetation is typically Mediterranean - olive groves, maquis (evergreen shrubland), holm oak, cypresses and pines. Flowering along the coast starts 2-3 weeks earlier than in Continental Croatia. The bura and jugo winds spread pollen across the whole Adriatic, and the olive 'on-years' that come every 2-3 years bring extreme concentrations.

Cities in Dalmatia
The pollen forecast for Dalmatia covers the following larger urban areas:
Typical symptoms
Allergy sufferers in Dalmatia most often report strong symptoms in May and June because of the olive - intense sneezing, a runny nose, watery eyes and swollen eyelids. In Split and Šibenik, cypress pollen affects sufferers as early as February. Pellitory (Parietaria) in the old town centres (Dubrovnik, Trogir) causes symptoms almost year-round - from April to October.
Protection and tips
In May and June, limit the time you spend in and near olive groves, especially on days with the jugo wind, when pollen travels far. Immunotherapy is available and effective for olive allergy, especially for permanent residents of Dalmatia. In the old town centres, avoid the damp stone walls where pellitory grows. Air conditioners with HEPA filters are essential during Mediterranean summers.
Frequently asked questions - Dalmatia
When does the olive flower in Dalmatia?
The olive flowers from mid-May to mid-July, peaking in June. In southern Dalmatia (Dubrovnik, the islands) flowering starts 2-3 weeks earlier than in the north (Zadar). Olive 'on-years' come every 2-3 years, when the olives flower en masse and pollen concentrations can exceed 500 grains/m³.
Is there a cypress allergy in Split?
Yes - cypress (Cupressus sempervirens) is widespread in Split, Zadar and other Dalmatian cities as an ornamental tree in parks and avenues. It flowers from February to April and causes symptoms in about 5-10% of Mediterranean allergy sufferers. It is often mistaken for a cold because it starts in winter.
What is pellitory and why does it cause allergy in Dubrovnik?
Pellitory (Parietaria officinalis and P. judaica) is a herbaceous plant that grows in the cracks of old stone walls - typically in Mediterranean urban settings such as Dubrovnik, Trogir and Split. It flowers almost continuously from April to October, which gives allergy sufferers intermittent symptoms for most of the year.
Is ragweed a problem in Dalmatia?
No, ragweed is marginal in Dalmatia. The Mediterranean climate and vegetation type do not suit ragweed - Dalmatian allergy sufferers who move from Slavonia usually notice a significant reduction in their late-summer symptoms.
How can I protect myself from olive pollen in June?
Follow the pollen forecast, stay indoors in the morning and on days with the jugo wind, and avoid olive groves. Start using antihistamines and nasal sprays preventively in late April. Immunotherapy is particularly useful for permanent residents of Dalmatia with strong symptoms.
