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