Pollen count Robertson residents check each morning
The Robertson pollen count today is 5 (Low). No single plant stands out in today’s readings; the Grass category is the one the index is led by. Tree pollen is the highest single category in the split at 0.6 (Low), ahead of grass pollen at 0.6 and weed pollen at 0.6. 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 tree pollen, reading noticeably higher than the rest, which is why the split is printed on every Robertson page.
Outside its main late-spring and early-summer window, grass pollen usually appears as a small background value rather than the driver of the total. A low grass reading alongside a higher weed or mold value is a typical off-peak pattern. Grass should be read from its own value on this page, not assumed from the calendar: the index reports today’s modelled value, and the modelled value outranks any general seasonal expectation.

When people ask about Robertson allergies, this is the number that answers them — one daily index built from today’s tree, grass, weed and mold readings for Robertson.
Allergies in Robertson follow the Wyoming 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 Robertson 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 Robertson allergy forecast: today reads 5 (Low), and the day-by-day outlook shows whether Robertson 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 Robertson today records is this same combined reading — tree, grass, weed and mold in one index.
The Robertson allergy count today is 5 (Low) — the same Total Pollen Index as the pollen count above, in one combined reading.

Pollen by type in Robertson
What is driving Robertson’s pollen today
The shape of today’s 5 (Low) is set by tree pollen at 0.6 (Low on its own scale) — about 33% of the four category readings added together, level with grass pollen at 0.6. Tree readings are the fastest-moving of the four in their season, because species pollinate in sequence — a tree-led total can change character within a week. Tree pollen leading in November runs against the usual calendar — the Wyoming tree chapter runs March to May — 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 Robertson, so the drivers have to be read from the category split above. The Wyoming guide’s account of Wyoming names sagebrush, the state’s signature allergen, flowering from August into October and peaking in September — 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 5 to 5, never changing band. Today’s 5 sits level with the window’s average of 5 — a steady window, in which one day reads much like the next.
Plants affecting Robertson now
Detailed plant-by-plant readings for Robertson 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.
Tree pollen is one of the categories with a non-zero reading today, at 0.6 (Low).
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 0.6 (Low).
In the High Basins pattern, the plants that typically shape this city’s year are river-corridor cottonwood and juniper, brief-summer meadow grasses, and sagebrush flowering late — named here as regional context only, not as today\u2019s measurements.

Robertson pollen through the year
The Robertson pollen year runs in chapters, set by the High Basins pattern and the Wyoming calendar. Trees come first: spring is a river-corridor season — cottonwood and juniper from March into May — because most of Wyoming’s trees grow where the water is. Grasses take the middle of the year: meadow and hay grasses carry the brief summer, from June into August. Weeds close it out: sagebrush flowers from August into October and peaks in September, and the first hard frost ends it.
The Wyoming allergy season guide names sagebrush, the state’s signature allergen, flowering from August into October and peaking in September. Spring is a river-corridor season — cottonwood and juniper from March into May — because most of Wyoming’s trees grow where the water is. Wind is a season-maker here: pollen routinely arrives from far beyond the local landscape, so a town’s bad day may be grown a basin away.
November falls between the main chapters of the Wyoming 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 Wyoming year, March to October — a compressed season, which is why its chapters arrive in quick succession. The full calendar is set out in the Wyoming allergy season guide.
How to read this index
Pollen Atlas reports the Robertson 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 whatever the month. 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.
Robertson in today’s national picture

Pollen totals are population numbers; symptoms are personal. The same reading can leave one Robertson resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Robertson, WY can test whether tree, grass, weed or mold is the category that matters for you — the four readings at the top of this page are the starting point for that conversation.
