Pollen Count in Providence, RI — Today
Updated Wednesday, October 21, 2026
The Providence pollen count today is 5 (Low). The main driver is Ragweed, with weed pollen at 1.2 today. The full split is tree pollen 0, grass pollen 0, weed pollen 1.2 and mold 1.2. 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 Wednesday, October 21, 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 Providence 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.

How to read this index
Pollen Atlas reports Providence on a Total Pollen Index from 0 to 100, built from separate tree, grass, weed and mold readings. The total is a summary, not an average of the four: a single strong category can lift it, and four quiet categories can hold it down even in a month when Providence, RI pollen is usually more active. Index values are supplied by AccuWeather data via Pollen Atlas and plant detail by the Google Pollen API, and figures update through the day, so a morning and an evening visit to this page can legitimately show different numbers.
