Is Mold Worse in Summer or Winter?

Mold is a year-round problem, but the risk of it growing in your home increases during the summer months due to several factors, such as warmer temperatures and summer rains. On the East Coast and Midwest, summer is often one of the worst seasons for mold growth due to high humidity levels. Bathrooms and kitchens are particularly prone to mold growth, as are areas with poor ventilation. Central air units can help reduce humidity, but if it's too cold inside and humid outside, condensation can occur around windows and doors, leading to mold growth.

Different types of molds thrive in different conditions, and some are more likely to grow in the winter months than others. Dead leaves in roof gutters can also cause mold growth because they trap moisture between them and the gutters. Using dehumidifiers and a meter to check humidity levels will help stop moisture accumulation and prevent mold from forming around windows. Although it doesn't grow at temperatures below zero, mold can survive in a dormant state and wait for spring to arrive.

The spores released by the fungus also cause allergy-like symptoms, making mold a major problem for people with respiratory diseases. Mold grows in specific conditions that require a high level of humidity and, if left untreated, can cause irreversible damage to walls, floors and ceilings. Because mold spores are so light and microscopic, cool afternoon breezes or even gentle winds can easily carry them from one place to another. While mold can grow any time of year, certain climates and seasons facilitate faster growth rates, which often vary by location. Opening windows and allowing free air circulation in your home during the summer helps prevent mold problems.

Unfortunately, people with mold allergies tend to experience more symptoms during the winter, when they are more likely to stay indoors for extended periods of time. High temperatures outside can also encourage mold growth, as it takes a few days to grow and increase its number. Mold allergies are common and can cause a variety of unpleasant symptoms, such as sneezing and runny nose, coughing, itchy eyes, nose, throat, or skin, and watery eyes. To prevent mold from growing in your home during the summer months, it's important to keep humidity levels low by using dehumidifiers and checking them regularly with a meter.

Additionally, make sure that your home is well-ventilated by opening windows when possible.
