Was today high ragweed pollen?
Checking
KINDA
Maybe — ragweed in Columbus is in its last week, but no live pollen count exists here to confirm.
Why
- Ragweed season here runs to the first frost, around Oct 27
- No ragweed count reported for Columbus; pollen data is Europe-only
- Today: 39°F low, 72°F high, so plants keep going
