What is driving East Islip’s pollen today

The shape of today’s 8 (Low) is set by weed pollen at 10 (Low on its own scale) — about 86% of the four category readings added together, 9 points clear of the next category, grass pollen at 1. A weed-led total is the classic late-year shape: tree and grass pollen have usually receded, leaving weed pollen — and on damp days mold — to make up most of what the index records. Weed pollen leading in November runs against the usual calendar — the New York weed chapter runs August to October — so today’s lead is the model outranking the pattern, and this page reports the modelled reading first.

Plant-level detail is not in today’s feed for East Islip, so the drivers have to be read from the category split above. The New York guide’s account of New York names birch and oak, preceded by elm and maple — the pollens behind readings of this shape in this state — and the split shows how much of today’s total each category is actually carrying.

Across the five-day window the Total Pollen Index runs from 8 to 18, never changing band. Today’s 8 sits 8 points below the window’s average of 16 — a moving window, worth reading day by day rather than from the average.

East Islip pollen through the year

Chapter by chapter, the East Islip pollen year runs like this:

• Trees open in late March and build to an oak-led peak in May.
• Grasses hold from late May into July.
• Ragweed builds from mid-August, peaks in September, and is ended by the first hard frost.
• Mold tracks the region’s humidity rather than a flowering calendar, and it fills the gaps between chapters.

The New York allergy season guide names birch and oak, preceded by elm and maple. New York City’s tree season typically opens one to three weeks ahead of Rochester’s, where Lake Ontario’s cold air delays spring along the shore. The AAFA’s 2025 report ranked New York City in the less-challenging half of its 100 metros, reflecting moderate overall burden despite a real spring peak.

November falls between the main chapters of the New York pollen year — the tail of one and the approach of the next — so the calendar alone explains little today, and the modelled split above carries the story. Between them, the three chapters cover 8 months of the New York year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the New York allergy season guide.

How to read this index

Pollen Atlas reports the East Islip pollen count on a Total Pollen Index from 0 to 100, built from separate tree, grass and weed readings. The total is a summary, not an average of the three: a single strong category can lift it, and three quiet categories can hold it down even in a month when East Islip, NY pollen is usually more active. Index values are a modelled pollen risk index computed by Pollen Atlas from open weather, vegetation and phenology data, calibrated against CDC/NAB season data, with plant detail by the Google Pollen API. The index is a modelled 0–100 scale, not a measured count, and figures update through the day, so a morning and an evening visit to this page can legitimately show different numbers.
