Tacoma Pollen Report
Tacoma sits on Puget Sound between the Olympics and the Cascades, in the wet, green heart of western Washington. Alder starts pollinating in late winter, birch and cherry follow in spring, the valley's grass fields drive a heavy June season, and the region's famous damp keeps mold spores active most of the year.

What drives allergies in Tacoma
Trees: alder, birch, and cedar (February – May)
Red alder (Alnus rubra) starts as early as February, followed by birch and big-leaf maple. Western red cedar adds to the mix.
Grasses: ryegrass and Timothy (May – July)
Western Washington's pastures and turf farms 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
Puget Sound's long damp season keeps Alternaria and Cladosporium active much of the year, peaking in fall and after prolonged rain.
