Pollen Type & Timing Tracker
Inspect concentrations for a selected plant instead of combining unlike pollen into a made-up allergy score.
Your pollen conditions inputs
Concentration forecasts are plant-specific and region-limited.
Load a location forecast optional
Manual example inputs work without a connection. Forecasts need a licensed location-data key set by the administrator.
Weather: Open-MeteoAir quality: CAMS. Place names: GeoNames. Pollen forecasts cover Europe during the supported season.

| Hour index | grains/m³ | Chosen comparison |
|---|---|---|
| 8 | 20 | Below chosen threshold |
| 9 | 35 | At/above chosen threshold |
| 10 | 50 | At/above chosen threshold |

| 12 | 25 | Below chosen threshold |
Concentration forecasts are plant-specific and region-limited. The optional provider currently has limited regional pollen coverage. No coverage is unavailable, not zero pollen. The entered comparison value is not an individual allergy threshold. The optional CAMS pollen feed covers Europe during pollen season; it is not a worldwide pollen observation feed.

How to use Pollen Type & Timing Tracker
- Inspect concentrations for a selected plant instead of combining unlike pollen into a made-up allergy score.
- The forecast provider’s pollen variables are limited to supported regions.
- The chosen threshold is simply a number for comparing the supplied concentrations.
Worked example
The supplied grass example ranges from 20 to 50 grains/m³. A chosen comparison of 30 is met by three known hourly values.
Formula, accuracy & limitations
Find the minimum, maximum and mean of known concentration values for the selected plant; count known hourly readings meeting the chosen numerical comparison. No universal clinical pollen category is assigned.

The primary result is rounded to two decimal places. Calculation tables show up to four and supporting metrics up to six. Very small nonzero values use scientific notation. Display rounding is not fed back into the arithmetic.
Official source and method context ↗Compare one pollen type at a time
Inspect concentrations for a selected plant instead of combining unlike pollen into a made-up allergy score. Paste a supplied series or explicitly request a supported forecast. Keep the plant, units and source consistent, because a grass concentration is not interchangeable with birch or ragweed.
Treat coverage as a separate result
The forecast provider’s pollen variables are limited to supported regions. A location can have weather data and no pollen data. In that case the loader explains the coverage limitation, and the calculator never fills a row with a zero that would imply absence of pollen.
Use a transparent numerical comparison
The chosen threshold is simply a number for comparing the supplied concentrations. Different plants, collection methods and people have different responses, so the page does not call that number a universal safe limit. Minimum and maximum identify conditions in the available list rather than diagnosing allergy severity.
Check whether an hour was actually supplied
Missing rows and NA values remain excluded from the known-value statistics. A list with only one known hour cannot describe a full day. The result includes the amount of available data so the apparent precision of a chart does not conceal missing coverage.
Frequently asked questions
Can I combine pollen types into one score?
This page reports one selected type. It does not invent a medically validated combined allergy score.
Why can my city have no pollen result?
Regional provider coverage is limited. Missing coverage does not mean zero exposure.
Is the comparison value a personal trigger?
It is user-chosen arithmetic and not a measured allergy threshold.
Does forecast pollen match my garden?
Model cells and monitoring methods have limited local resolution; no exact property-level exposure is claimed.
