Worst grass pollen season in 45 years hits southern and eastern Norway

Southern and eastern Norway are experiencing the most severe grass pollen season in 45 years, with hot, dry, and sunny weather creating ideal conditions for pollen spread, the Norwegian Asthma and Allergy Association (NAAF) has warned.

NAAF, which oversees national pollen forecasts, reports rising grass pollen levels across the country, with some areas already recording extremely high concentrations. In Oslo, this year’s season ranks among the most intense in nearly half a century.

“With the current weather forecast, everything points to many allergy sufferers facing significant discomfort in the coming days,” the association stated in a press release.

Senior researcher Nestor González Roldán of NAAF said the next few days would likely see strong pollen dispersal. “For many, this could be among the most challenging days of the season so far,” he added.

Grass pollen season typically lasts much of the summer, though levels can vary widely by location and week, depending on weather. Rain does not necessarily signal the end of the season, Roldán noted.

He advised regular use of allergy medication throughout the season for optimal effect, even on days with milder symptoms, and recommended following pollen forecasts to adjust outdoor activities accordingly.
