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 France allergy season guide is published yet, so the seasonal context here follows the Continental West regional pattern.
