Species driving Delta’s grass pollen

The modelled data reports grass as one combined index — there is no species-by-species split for grass anywhere in the data, so this page does not invent one. Today’s modelled grass index for Delta is 0.6 (Low), and the 5-day overall trend above shows the shape of the week.

What this grass pollen level means

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

Enjoy outdoor activities.

Grasses run from May, peaking in late spring and early summer. This month sits outside the usual grass pollen window for the Pacific Northwest pattern, so today’s grass pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. No British Columbia allergy season guide is published yet, so the seasonal context here follows the Pacific Northwest regional pattern.
