This increase in humidity has tangible effects on the perceived temperature, often making it feel warmer than the actual air temperature. For instance, a temperature of 75F (24C) can feel several degrees warmer with higher humidity due to the reduced efficiency of evaporative cooling from the skin.

The increasing humidity in May impacts various aspects of life in Baltimore. Outdoor activities may require adjustments, such as increased hydration and more frequent breaks. The higher moisture content in the air can also affect infrastructure, potentially accelerating corrosion and impacting the performance of certain materials. Agriculture and horticulture are also influenced by the rising humidity, as it can promote the growth of certain plants while increasing the risk of fungal diseases. Understanding and anticipating this increase in humidity allows for better planning and adaptation to the changing weather conditions. For example, choosing breathable clothing and using dehumidifiers in homes can mitigate some of the less desirable effects of high humidity.

In summary, the rise in humidity during May in Baltimore is a significant component of the overall weather pattern.
