Pollen Atlas models the daily detail as an overall index: day-by-day splits by individual pollen type are not part of the modelled data, so this table shows Machen’s overall trend across the week. Today’s tree pollen reading is the headline above.

Species driving Machen’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 10 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

Plants affecting Machen now — tree pollen

Detailed plant-by-plant readings for the tree pollen category were not returned in today’s source data for Machen. The type summary stands: tree pollen reads 10 (Low) today.

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.
