Species driving Sevelen’s grass pollen

As regional context only — not as today’s readings — in the Continental West pattern, the plants that typically shape this city’s year are early hazel and alder, a birch-led spring, late-spring grasses, and late-summer mugwort and ragweed.

What this grass pollen level means

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