Oakland Pollen Report
Oakland's hills are covered in its namesake trees — coast live oak — and the East Bay's Mediterranean climate runs a long, layered allergy calendar. Oak and bay laurel drive the spring, grass-covered hillsides pollinate into early summer, and the mild, damp winters keep mold active. Microclimates mean your symptoms can vary neighborhood to neighborhood.

What drives allergies in Oakland
Trees: oak, bay, and acacia (January – May)
Coast live oak (Quercus agrifolia) is Oakland's signature spring allergen; California bay laurel, acacia, and ornamental birches contribute from winter onward.
Grasses: hillside grasses (March – June)
The East Bay hills' wild oat and rye grass pollinate through late spring, peaking in May.
Weeds: modest (August – October)
Ragweed is lighter than inland; sagebrush, plantain, and pigweed contribute in late summer and fall.
Mold: winter and fog-linked
Winter rains and summer fog keep Alternaria and Cladosporium active, with peaks in the wet season and during leaf drop.
