Pollen count Meridian residents check each morning
The Meridian 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. 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 tree pollen, reading noticeably higher than the rest, which is why the split is printed on every Meridian page.
Higher-elevation Mountain West cities generally run a shorter outdoor pollen season than the coasts or the South, with the main tree and grass activity compressed into the warmer months. Autumn and winter pages in this region are therefore commonly quiet, with low totals built from small weed and mold values. A low reading in this region and season is the expected pattern, and any future rise will show first in the category split and the forecast, not in the headline alone.

This is the pollen count Meridian residents check each morning, built from the day’s tree, grass, weed and mold readings.

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

Pollen by type in Meridian
What is driving Meridian’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 Colorado tree chapter runs February 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 Meridian, so the drivers have to be read from the category split above. The Colorado guide’s account of Colorado names juniper, arriving ahead of the local tree season, and the ragweed and sagebrush-family weeds of late summer — 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 Meridian now
Detailed plant-by-plant readings for Meridian 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 Mountain West pattern, the plants that typically shape this city’s year are spring trees and late-spring grasses in a compressed warm-season window — named here as regional context only, not as today\u2019s measurements.

Meridian pollen through the year
Three chapters make the Colorado pollen year, and Meridian follows them in the Mountain West order. The tree chapter: juniper can arrive in late winter, and the main tree wave builds in spring — as late as April at Denver’s altitude. The grass chapter: grasses follow in a compressed early-summer run. The weed chapter: ragweed and sagebrush-family weeds close the year from late summer.
Altitude compresses Colorado’s season rather than removing it: the waves arrive late — Denver’s tree pollen typically builds in April — and end with early frosts, but they run in a tight sequence. The season ends with the first hard frosts, which stop the late-summer weeds — Denver usually reaches frost in fall, while mountain towns can frost far earlier. The Colorado guide singles out juniper, arriving ahead of the local tree season, and the ragweed and sagebrush-family weeds of late summer.
November falls between the main chapters of the Colorado 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 9 months of the Colorado year, February to October — leaving a quiet gap of roughly 3 months in the depth of the off-season. The full calendar is set out in the Colorado allergy season guide.
How to read this index
Pollen Atlas reports the Meridian 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.
Meridian in today’s national picture
At 5 (Low), Meridian ranks joint 86157th of the 90896 cities Pollen Atlas tracks today — in the middle of the national table. The highest reading in the country today is Serpa, Portugal at 53, and the lowest is Galiakberovo, Russia at 5. The whole table spans 48 points today — a wide-open day, when the top and bottom of the table are effectively in different seasons.
Around Meridian: Lone Tree, CO (1 miles away) reads 5 (Low); Grand View Estates, CO (2 miles away) reads 5 (Low); Meridian Village, CO (2 miles away) reads 5 (Low). Meridian reads exactly level with its nearest tracked neighbour today. Across Colorado’s 479 tracked cities, today runs from 5 in Parker to 32 in Dillon.
Pollen totals are population numbers; symptoms are personal. The same reading can leave one Meridian resident untouched and floor another, depending on which pollens they are sensitised to. If this pattern finds you every season, allergists in Meridian, CO 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.
