Olympia Pollen Report
Olympia sits at the southern tip of Puget Sound, surrounded by the wettest, greenest landscape in the country. Alder starts pollinating in late winter, birch and maple follow in spring, pasture grasses drive a heavy June season, and the region's famous damp keeps mold spores active most of the year.

What drives allergies in Olympia
Trees: alder, birch, and cedar (February – May)
Red alder (Alnus rubra) starts as early as February, followed by birch, big-leaf maple, and western red cedar.
Grasses: ryegrass and Timothy (May – July)
Western Washington's pastures and turf drive a heavy June grass season — the South Sound's roughest stretch.
Weeds: modest fall (August – October)
Ragweed is lighter than east of the Cascades; plantain, sorrel, and nettle contribute through late summer.
Mold: the region's constant
The South Sound's long damp season keeps Alternaria and Cladosporium active much of the year, peaking in fall and after prolonged rain.
