Pollen count Smithsburg residents check each morning
The Smithsburg pollen count today is 16 (Low). The main driver is Ragweed, with weed pollen at 21 today. Weed pollen leads the split at 21 (Low on its own scale), followed by tree pollen at 0.6 and grass pollen at 0.6. Below, the plant detail and the multi-day outlook show whether today is the pattern or the exception. Pollen Atlas updated this count on Friday, November 6, 2026.
A Low band on the Pollen Atlas index means the Total Pollen Index has stayed in the lower part of the 0–100 scale. Readings in this band are built from low individual category values rather than from one large spike, and the category split above matters more than the headline number: a low total can still contain one category, such as weed pollen or mold, reading noticeably higher than the rest, which is why the split is printed on every Smithsburg page.
Fall is ragweed season across most of the United States: ragweed plants release pollen from late summer into autumn, and weed pollen is typically the last major outdoor pollen category to fade as the weather cools. That pattern is why an autumn total is so often weed-led even when the headline number is low — tree and grass pollen have usually receded by then, leaving weed pollen, and on damp days mold, to make up most of what the index records. In the Northeast, autumn weed pollen typically winds down as colder nights arrive, so late-season totals can change quickly from week to week.

Pollen by type in Smithsburg
What is driving Smithsburg’s pollen today
The shape of today’s 16 (Low) is set by weed pollen at 21 (Low on its own scale) — about 95% of the four category readings added together, 20.4 points clear of the next category, tree pollen at 0.6. 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 Maryland 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 Smithsburg, so the drivers have to be read from the category split above. The Maryland guide’s account of Maryland names oak, the mid-Atlantic heavyweight, peaking hard in late April and May — 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 16 to 23, never changing band. Today’s 16 sits 6 points below the window’s average of 21.6 — a moving window, worth reading day by day rather than from the average.

Smithsburg pollen through the year
Three chapters make the Maryland pollen year, and Smithsburg follows them in the Northeast order. The tree chapter: trees open in late March and build to an oak-led peak in May. The grass chapter: grasses hold from late May into July. The weed chapter: 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.
Around the Chesapeake, sustained tidewater humidity grows mold that fills the gap between the grass fade and the ragweed build. Garrett County’s western mountains run weeks behind the bay in spring and finish weeks earlier in fall, with harder, sooner frosts. The Maryland guide singles out oak, the mid-Atlantic heavyweight, peaking hard in late April and May.
November falls between the main chapters of the Maryland 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 Maryland year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Maryland allergy season guide.
How to read this index
Pollen Atlas reports the Smithsburg 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 Smithsburg, MD 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.
