Species driving Potters Bar’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 25 (Low) today.

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.
