Ambrosia, mugwort and grasses are nearing the end of their flowering season. Heavy rains have washed the last pollens to the ground. The risk of allergy will no longer exceed the low level along the Rhône valley. Elsewhere, the allergy risk is nil.
Cupressaceae (cypress, cedar, juniper) are already present, and will be responsible for a low allergy risk around the Mediterranean.
Cedars are the last trees to bloom, and their pollen can cover outdoor surfaces (balconies, cars, sidewalks, windows, roads, etc.) with a yellow powder, but without bothering allergy sufferers, as their allergenic potential is low.
