Species driving Opmeer’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 Opmeer is 0.6 (Low), and the 5-day overall trend above shows the shape of the week.

As regional context only — not as today’s readings — 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.

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