Local Mold Conditions
Mold in Maryborough is shaped by moisture averaging 38.2% and a warm climate — supportive of growth across much of the year, though peak summer heat can exceed optimal levels for Cladosporium. Organic matter is present at a moderate level — enough to sustain growth without being exceptional. Growth potential is limited for both species, with Alternaria only slightly less constrained.
Mold in Maryborough tracks the overlap of adequate moisture and manageable temperature — warmth is helpful, but summer heat can exceed what Cladosporium tolerates. Soil moisture reaches 55.4% in March and is lowest in September — the shoulder seasons offer the best balance of moisture and manageable temperature. Both Cladosporium and Alternaria disperse spores in dry, breezy conditions, so airborne levels peak after the moisture high, in the drying-out phase.

Frequently Asked Questions About Mold in Queensland
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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
