When is pollen worst in Malta?

Malta runs the classic three-wave calendar: tree pollen Mar–May, grass May–Jul, then ragweed Aug–Oct. The two worst stretches are the spring tree peak and the late-summer ragweed peak. Currently, ragweed pollen is what's driving counts this month.

What's in the air in Malta right now?

In August, ragweed pollen is in season in Malta — the dominant allergen you're likely reacting to right now. A live count, when available, confirms the day's actual reading; this reflects the typical peak windows for Malta's high-elevation Mountain West climate.

Is tree or grass pollen higher in Malta in spring?

In spring, tree pollen leads in Malta — trees pollinate Mar–May, ahead of grass (May–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 Malta's pollen season distinctive?

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.

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.

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 23 (early June), grass from week 18 (early May) to week 31 (early August), and ragweed from week 31 (early August) to week 40 (early 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. Counts run highest on warm, dry, windy mornings and drop after rain, which washes pollen out of the air — reported on the None / Low / Moderate / High / Very High scale.
