European aerobiologists operate since many years pollen monitoring devices and have built up common international networks for the benefit of allergy sufferers. Continuous scientific research follows the evolution that we know from improvement of weather forecasts over decades. Be sure we do our best to provide most accurate information about pollen loads and tailored personalized advice for your well being and planning of leisure activities.

Situation and medium-term forecast for Hungary


Hungary has a continental climate, with hot summers with low overall humidity levels but frequent rainshowers and mildly cold snowy winters. Average annual temperature is 9.7 °C (49.5 °F). The average yearly rainfall is approximately 600 mm. Wet weather coming in from the west is tempered by drier warmer winds rising up from the Mediterranean and cooler temperatures coming from the Carpathians and Alps nearby. As a result of these complex weather patterns, thePannonian Region exhibits a mosaic vegetation structure instead of the more classic zonal arrangements that one sees in other biogeographical regions. The Pannonian Biogeographical Region (Carpathian Basin), especially Hungary is the most affected area in Europe regrading ragweed (Ambrosia artemisiifolia) the most allergenic wind-polliated plant). The assessment and evaluation of the population exposure to ragweed pollen is of high importance. This area is the main source of long-distance wind-transported ragweed pollen for many North and West-European Country. Other important aeroallergens in Hungary are: alder (Alnus), hazel (Corylus), birch (Betula), grasses (Poaceae).

The Hungarian Aerobiological Network was founded in 1992. The daily airborne pollen concentration has been monitored since that time and the network has been widened continuously, since 2005 it has got 19 monitoring stations. The monitoring stations are almost evenly distributed throughout the country. The data are collected, evaluated and stored by the National Institute of Environmental Health, Budapest.


Aerobiological monitoring method:

Type of pollen trap: 7-day Hirst-type trap (Burkard-trap)

Number of pollen traps in the network: 19

Sampling height above ground (m): avg 20.5 m, min 12, max 40.

Flow rate of the pollen trap and frequency of control: 10 l/min, 1/week

Annual sampling period: start date: 28.Jan.2008. (in 13 stations).

Annual sampling period: end date: 09. Dec.2008. (in 11 stations).

Microscope magnification 40x

Sampling time per slide ( 0 - 24h, 8 - 8h) 8-8h

Counting method: horizontal (longitudinal) for pollen grains; 12×2 fields (0.25×0.25 mm) for fungal spores

Resolution: bi-hourly, 24h avg.

Number of lines/random fields counted: 2

Area counted per slide for pollen grains: 48 mm2, for fungal spores 1.5 mm2

Minimum required pollen types 32

Minimum required fungal spores: 3 (Alternaria and Cladosporium and Epicoccum)

Quality control test for pollen identification: 1/year , with repeated analysis of selected slides by analysts of the central laboratory

Disemination of aeroallergen data:

-Weekly pollen report (1/week, 1/day in one station)

-Ragweed pollen report (1/day) + ragweed pollen alert

-UNIPHE interface: pollen indicators (Ambrosia, Alnus, Betula, Poaceae- developed in the collaboration with the WHO/CEHAPHIS) could be applied for scientific and public (patient) information.

Pollen load map of Europe for


For planning your vacation, we have produced maps that show Pollen loads in Europa in different time periods. These maps show measured pollen counts from the past 10-15 years, based on records from over 300 pollen-monitoring stations in Europe.
Per month you can find three maps that show you the potential pollen loads. The representations are weighted according to severity of the expected allergic symptoms. White areas show parts of Europe where there is no risk from a particular pollen type, green represents areas with low amounts of a certain pollen type, and yellow to dark red marks areas with increasing pollen loads from moderate to very high. Click on the map to zoom in.
