Juneau, Alaska Pollen Count

Frequently asked

When is pollen worst in Juneau?

Juneau's season is short and front-loaded: a sharp tree burst Apr–Jun is the main event, grass is brief (Jun–Jul), and ragweed (Aug–Sep) is nearly an afterthought. Miss the spring tree window and you've largely missed the year. Currently, tree and grass pollen is what's driving counts this month.

What's in the air in Juneau right now?

Right now tree pollen leads in Juneau at a Very Low (1/5) level. The species actually in the air today: Birch, Pine, and Oak. On a quiet live day, Juneau's seasonal calendar fills in what's typically airborne this time of year.

Is tree or grass pollen higher in Juneau in spring?

In spring, tree pollen leads in Juneau — trees pollinate Apr–Jun, ahead of grass (Jun–Jul). The handoff is the tail of the tree window: tree counts taper as grass climbs, so an early-spring flare is more likely tree pollen and a late-spring one more likely grass.

What makes Juneau's pollen season distinctive?

Juneau sits in the subarctic Alaskan zone, which means a compressed, birch-driven calendar — the season is short and tree-dominated, with grass brief in midsummer and ragweed nearly absent. That shapes when symptoms hit and which allergen to watch.

How do I reduce pollen exposure in Juneau?

Through Juneau's peak windows (tree Apr–Jun, grass Jun–Jul, ragweed Aug–Sep), keep windows shut and run AC on recirculate; counts run highest on dry, warm, windy mornings, so push outdoor activity to late afternoon or just after rain, which clears pollen from the air. A HEPA purifier indoors, a saline rinse after being outside, showering before bed, and starting antihistamines a week or two before your worst local window all measurably cut symptoms.

What pollen index counts as high?

Pollen is reported on a categorical scale — None, Low, Moderate, High, and Very High. "High" and above means most allergy sufferers notice symptoms even with brief outdoor exposure, and sensitized people should limit time outside and pre-medicate. "Low" to "Moderate" usually only affects highly sensitive individuals.
