Low Mold Allergy Risk

Lower humidity-driven mold risk scores higher using relative humidity, indoor dampness, and precipitation proxies.

Scale0-100

Higher values rank better for this score.

How It's Calculated

The latest published score is normalized to a 0-100 scale. The method below explains what the score rewards, with technical source metadata available for audit.

Scoring Method

How the ranking is built

Low Mold Allergy Risk is an environmental proxy for places less favorable to dampness-driven mold conditions.

  1. 1

    Mold burden is a weighted blend: 32% hours at 80% RH or higher, 28% annual precipitation, 22% indoor-70F hours at 60% RH or higher, and 18% annual RH excess.

  2. 2

    The burden is confidence-shrunk when station evidence is weaker.

  3. 3

    The score is inverse percentile-rank normalized over the full scored distribution, so lower proxy risk scores higher.

What This Score Means

Low Mold Allergy Risk is an environmental proxy for places less favorable to dampness-driven mold conditions.

Statistics Feeding This Score

  • Hours at 80% RH or higher

    Annual hourly-normal count for very damp air.

    Source: NOAA U.S. Climate Normals, hourly
  • Annual precipitation

    Annual precipitation in inches, joined from the annual climate-normal run.

    Source: NOAA U.S. Climate Normals, annual/seasonal
  • Indoor-70F hours at 60% RH or higher

    Outdoor moisture converted to a 70F indoor relative-humidity proxy.

    Source: Derived from NOAA hourly normals

Source Data

Source: NOAA U.S. Climate Normals, hourlyNOAA NCEI 1991-2020 hourly station normals used for dew point, muggy-hour, and heat-index humidity proxies.Source: NOAA U.S. Climate Normals, annual/seasonalNOAA NCEI 1991-2020 station normals matched to places using nearby stations, with distance and elevation mismatch penalties.

Known Limits

  • Hourly station normals are environmental proxies, not forecasts or indoor-environment measurements.
  • Nearby stations are weighted by distance and elevation fit, then lower-confidence estimates are shrunk toward the all-place mean.
  • Allergy-risk scores do not include local spore counts, medical outcomes, building ventilation, or indoor humidity.
