Local Mold Conditions
With woodland on around 72% of the land, the area around this location in New Haven offers mold plenty of organic material to grow on. The forest floor is the biggest reservoir, with fallen oak and maple leaves, bark and dead wood breaking down slowly in the damp shade. The damp ground along a lake or pond nearby keeps leaf litter and plant debris moist for longer.
On fallen leaves and dead wood, Cladosporium, the most widespread outdoor mold, is active from April to October and reaches its peak in July, at around 24°C. Warmer weather favors Alternaria, which is present from May to September and peaks in July. Outdoor mold is largely dormant from December to March, when temperatures stay under 5°C. Daily levels tend to climb through dry, windy afternoons and drop during prolonged rain.

Frequently Asked Questions About Mold in Connecticut
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. |
