Can weather stand in for a mold count?
Only roughly: warm, dry, windy, no rain in two days after a wet spell is when dry-air spores fly, and the result is always an estimate.
What it is
A guess at dry-air spores from the weather alone: warm, dry, windy, no rain in two days, after a wet spell. Each condition met adds a point, out of five.
How it affects breathing
- Evidence. The same spores as mold, by a stand-in: a mechanism, thin data. It can raise a suspicion and never confirm one.
- How likely. The same as Mold, for people sensitized to mold.
- What helps. The same as Mold.
How Breathing Index measures it
Your Breathing Index counts the five conditions against each hour’s forecast, in season only, and always marks the result as an estimate, since no instrument looked at the air.
Where the number comes from
No instrument looked at the air. Five weather conditions off the forecast, counted.
