Ajax Tree Pollen Count: 5-Day Forecast

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 Ajax’s overall trend across the week. Today’s tree pollen reading is the headline above.

Species driving Ajax’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 0.6 (Low) today. The plant-by-plant detail that is available, from the Google Pollen API, is in the next section.

What this tree pollen level means

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

Enjoy outdoor activities.

Trees run from March into May, later near the big lakes. This month sits outside the usual tree pollen window for the Midwest & Great Lakes pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No Ontario allergy season guide is published yet, so the seasonal context here follows the Midwest & Great Lakes regional pattern.
