Wednesday, August 26 · mostly ragweed

Thirty-odd miles north, and usually ahead of the city on tree pollen in spring. Useful as a warning, not as your number.

What this doesn’t tell you

One sampler on one roof in Midtown, collecting over a full 24 hours. It is not a reading for your block and not a reading for right now — wind, rain and the trees on your own street all move it. A low count citywide can still be a bad morning under a plane tree.

Counts are posted by hand during the season and stop for the winter. Nothing here is medical advice.
