How Malta’s pollen count works

The calendar above is tuned to Malta’s high-elevation Mountain West climate, not a national average: tree pollen runs from week 10 (early March) to week 22 (late May), grass from week 18 (early May) to week 30 (late July), and ragweed from week 31 (early August) to week 43 (late October) here — a 244-day combined pollen season. Those windows are why ragweed pollen is the one in season in Malta right now.

No live count is wired up for Malta today, so the seasonal calendar above is your guide to which allergen is in season.

Frequently asked

When is pollen worst in Malta?

Is tree or grass pollen higher in Malta in spring?

Malta sits in the high-elevation Mountain West zone, which means short, sharp seasons set late by elevation, with sagebrush adding to the late-summer weed load. That shapes when symptoms hit and which allergen to watch.
How do I reduce pollen exposure in Malta?
Through Malta's peak windows (tree Mar–May, grass May–Jul, ragweed Aug–Oct), 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.
