CAMS model forecast from 6 October at 01:00 BST, weather from the ECMWF model run of 6 October at 07:00 BST. Model values are shown unchanged; this is not a measurement or an official forecast.

Level scale (daily mean concentration, grains/m³; US National Allergy Bureau scale, AAAAI, as the UK has no open national scale): trees moderate from 15, high from 90, very high from 1500; grass from 5, 20 and 200; weeds (mugwort) from 10, 50 and 500. People with hay fever can have symptoms at low levels too.

Hay fever in Glasgow

Glasgow's hay fever season is later and shorter than in England. Birch is the main tree pollen in Scotland, and in Glasgow it usually peaks from late April into May, about two weeks after London. Grass follows from June, peaking in late June and July. The frequent Atlantic rain often keeps counts lower than in the drier east of Scotland, and the highest days tend to come in warm, settled spells with an easterly wind, when the air reaches the city over the farmland of central Scotland.

Air quality in Glasgow

CAMS forecasts a daily mean of 4.7 µg/m³ of PM2.5 today, below the WHO 24-hour guideline of 15 µg/m³. Air pollution can make hay fever and asthma symptoms worse. Official forecast: Defra UK-AIR.

Pollen calendar and where the data comes from

A typical UK year: hazel and alder from January to March, birch from late March to mid-May (the main tree allergen, about one in four hay fever sufferers react to it), grass from mid-May to July, usually in two peaks (early to mid-June and early July), and weeds such as nettle, dock and mugwort from June to September. Scotland runs about two weeks behind the south of England. CAMS does not model hazel, nettle or plane tree.

CAMS (a European ensemble of models, median) computes every hour how much alder, birch, grass, mugwort, ragweed and olive pollen is in the air over Europe, on a grid of about 10 km, four days ahead. On the map, particles start where the model puts pollen in the air today and drift on the ECMWF wind. UK pollen calendar
