Species driving Tregynon’s tree pollen

Species-level counts are not part of the modelled data Pollen Atlas publishes — the modelled index is reported per pollen type, not per species — so this section gives the type summary: tree pollen reads 7 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

In the Atlantic West pattern, the plants that typically shape this city’s year are early hazel and alder, a spring birch and oak wave, late-spring and summer grasses, and a modest late-summer weed finish — named here as regional context only, not as today’s readings.

Plant detail returns here automatically on any day the feed includes it.

What this tree pollen level means

Low risk. Keep windows open; consider allergy meds only if sensitive.

Enjoy outdoor activities.

Hazel and alder can open as early as February in mild winters, and the main tree wave — birch, then oak — builds through spring to a May peak. This month sits outside the usual tree pollen window for the Atlantic West pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No United Kingdom allergy season guide is published yet, so the seasonal context here follows the Atlantic West regional pattern.
