What seasonal time frame typically sees an increase in mould growth indoors?

Mould growth indoors is most commonly associated with the spring months. As temperatures begin to rise and humidity levels increase during this time, ideal conditions for mould growth are created. The warmer weather in spring often leads to increased moisture in the air and potential water accumulation from melting snow or rain, which are conducive environments for mould spores to thrive.

In addition, many people start to engage in spring cleaning, which might disturb mould that has settled in less visible areas, thus making it more noticeable. This interaction between increased humidity, temperature, and the potential for water accumulation points to why spring is the seasonal timeframe that typically sees a rise in indoor mould growth.

While other seasons can also see mould growth due to varying conditions, it is during spring that the combination of warmth, moisture, and increased indoor activities most significantly promotes the proliferation of mould.
