Local Mold Conditions
Organic material for mold to grow on is plentiful around this site in Angleton, mainly in the woodland. With woodland on around 54% of the land, there is a deep layer of fallen oak leaves, twigs and rotting wood that keeps moisture close to the ground. Dead leaves, grass clippings and compost in gardens add further material close to homes.
Most outdoor mold spores here are Cladosporium, which grows on the woodland litter through most of the year and is most plentiful in May, when temperatures average 25°C. Alternaria needs more warmth and is most abundant in July. Counts are lowest around January, when temperatures average about 11°C. Day to day, spores peak on dry, breezy afternoons after dew or light rain.

Frequently Asked Questions About Mold in Texas
Why do I still have allergy symptoms after the pollen season?
Allergy symptoms after the main pollen season may be caused by mold spores. Outdoor mold levels can remain high into late summer and autumn, when pollen levels are already falling. Mold allergy can cause symptoms similar to pollen allergy, including sneezing, a runny or blocked nose, itchy eyes, coughing, and wheezing.
What are mold spores and why do they cause allergies?
Mold spores are tiny particles released by fungi into the air. When inhaled, they can trigger an allergic reaction in sensitive people. Common symptoms include sneezing, a runny or blocked nose, itchy or watery eyes, coughing, and wheezing.
When are mold spore levels highest?
Outdoor mold spore levels often increase during warm and humid conditions, particularly when there is plenty of decaying vegetation. Levels can vary considerably with weather, season, vegetation, and location, and some types of mold are more common during particular times of the year, e.g. in the Fall.
How can I reduce my exposure to mold spores?
If you are sensitive to mold, check local mold spore levels and forecasts before spending long periods outdoors. On high-risk days, reducing time around dense vegetation, compost, fallen leaves, and other sources of decaying plant material may help limit exposure.
Understanding the Scale
The 0–100 mold scores represent risk levels, not direct mold measurements. Higher scores indicate higher risk.
Mold
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
