Today's allergy situation depends on your location, but here is a quick overview by region for August 17, 2025:

• UK: Moderate weed pollen levels are present today in some regions such as Strathclyde, West Midlands, Wales, and Dumfries, Galloway, Lothian & Borders. Most other areas have low pollen counts.

• Germany: In Berlin, pollen levels are low, with only minor grass pollen risk and no tree pollen risk. In Munich, pollen count is essentially zero for tree, grass, and weed pollen.

• Ireland: Medium concentrations of grass and weed (nettle) pollen are expected, as well as moderate levels of the fungal spore Cladosporium.

• USA: Pollen levels are "medium-high" across much of the country, particularly for weed pollen (notably ragweed, which peaks in late summer). Local spikes may occur, especially in the Midwest, Northeast, and rural areas.

• Australia (Melbourne & Perth): Grass pollen levels are low for today.

For most of the Northern Hemisphere , the dominant allergen in late summer is weed pollen , particularly ragweed in the US and nettle/other weeds in the UK and Ireland. If you are allergic to weeds or ragweed, you are most likely to notice symptoms today, especially in moderate or medium- high risk zones.
