In Grindelwald, pollen season can begin in February or March, depending on the weather. Hazel and alder trees release pollen first. Warm days may bring it earlier, while snow and cold can delay it in the valley.

Spring pollen levels often rise in April and May, though higher mountain areas may bloom later. Birch, ash, and beech trees release pollen. This pollen can travel on the wind and bother people with allergies.

In early summer, usually from late May through July, grasses release much of the pollen around Grindelwald. Meadow grasses grow across fields and slopes. Their pollen may be strongest on warm, dry, breezy days in the area.

From late July into September, weeds such as plantain, nettle, and mugwort can release pollen. Their season is often shorter and lighter than grass season. Cool weather or early snow may end pollen release sooner.
