How pollen levels are scored
Thresholds differ by plant, because the amount of pollen it takes to provoke symptoms differs by plant. A count of 20 is a moderate grass day and a very high ragweed one.
| Pollen | Low | Moderate | High | Very high | Usually in the air |
|---|---|---|---|---|---|
| Alder | 1–9 | 10–99 | 100–999 | 1000+ | January to March |
| Birch | 1–9 | 10–99 | 100–999 | 1000+ | March to May |
| Olive | 1–49 | 50–199 | 200–999 | 1000+ | April to June |
| Grass | 1–19 | 20–49 | 50–199 | 200+ | May to August |
| Mugwort | 1–9 | 10–29 | 30–99 | 100+ | July to September |
| Ragweed | 1–9 | 10–19 | 20–49 | 50+ | August to October |
How these figures are produced
These counts come from the Copernicus atmospheric monitoring service, which models pollen concentrations on a grid across Europe, sampled at the coordinates of Frías. They are modelled values rather than grains counted at a pollen trap in the town, so neighbouring localities in the same grid cell will show similar figures, and a tree in flower on your street can matter more than the number here. Treat them as a regional indication. They are not medical advice: if symptoms are severe or persistent, speak to a doctor or pharmacist.
