Pollen count Severn residents check each morning
The Severn pollen count today is 8 (Low). The main driver is Ragweed, with weed pollen at 11 today. The full split is tree pollen 0.6, grass pollen 0.6, weed pollen 11. The sections below break that headline number down by plant, by day and by what the band means in practice. 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 Severn 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.

Severn allergies today
Severn allergies today are set by the same reading as the pollen count above: the Total Pollen Index is 8 (Low), driven mainly by Ragweed. When people ask about Severn allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Severn.
Allergies in Severn follow the Maryland calendar set out below — the chapters, the plants behind them, and the 5-day forecast on this page show whether today is typical for the season or an exception to it. If you are checking allergies today in Severn before heading outdoors, the split at the top of this page is the part to read: it shows which pollen is doing the work today, not just how high the total sits.
Read the five-day table on this page as the Severn allergy forecast: today reads 8 (Low), and the day-by-day outlook shows whether Severn allergies are set to ease or build across the week — the days to plan outdoor time around are the ones where the index steps down, not just today.
In practice, the allergy count Severn today records is this same combined reading — tree, grass, weed and mold in one index.
The Severn allergy count today is 8 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Severn
What is driving Severn’s pollen today
The shape of today’s 8 (Low) is set by weed pollen at 11 (Low on its own scale) — about 90% of the four category readings added together, 10.4 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 Severn, 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 8 to 21, never changing band. Today’s 8 sits 10 points below the window’s average of 17.8 — a moving window, worth reading day by day rather than from the average.
Plants affecting Severn now
Detailed plant-by-plant readings for Severn were not returned in today\u2019s source data, so this section summarises the pollen types the index above is built from instead of listing individual plants.

Grass pollen is one of the categories with a non-zero reading today, at 0.6 (Low).
Weed pollen is one of the categories with a non-zero reading today, at 11 (Low).
In the Northeast pattern, the plants that typically shape this city’s year are spring trees, late-spring grasses and late-summer ragweed — named here as regional context only, not as today\u2019s measurements.
Plant detail returns here automatically on any day the source data includes it.

Severn pollen through the year
The Severn pollen year runs in chapters, set by the Northeast pattern and the Maryland calendar. Trees come first: trees open in late March and build to an oak-led peak in May. Grasses take the middle of the year: grasses hold from late May into July. Weeds close it out: 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 Maryland allergy season guide names oak, the mid-Atlantic heavyweight, peaking hard in late April and May. 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.
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 Severn 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 Severn, 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.
Severn in today’s national picture

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Severn resident untouched and floor another, depending on which pollens they are sensitised to.
