May weather forecast
Maryland, USA

May ushers in a new season in Maryland, characterized by a marked increase in warmth and a departure from the cooler temperatures of spring. This month is a prelude to the hot and humid summer, and the weather becomes distinctly warmer, with temperatures occasionally reaching above 100°F (37.8°C) in some areas.

The western region, including places like Cumberland, begins to experience more moderate temperatures, leaving behind the colder and snowier conditions of previous months. Snowfall is virtually absent across the state, and frost becomes an increasingly rare phenomenon.

The influence of the Atlantic Ocean, coupled with the warming effect of the Appalachian Mountains, contributes to the overall rise in temperatures. These geographical factors create a conducive environment for the growth of lush vegetation and flowering plants, enhancing the natural beauty of the state.

Comparatively, May offers more stable and predictable weather than April. The fluctuations between warm and cold fronts become less pronounced, leading to a consistent warming trend. Outdoor activities become more appealing as the days lengthen, and the sun shines with greater intensity.

Driving conditions continue to improve, free from the challenges of winter's slush and ice. The anticipation of summer's full embrace grows, as May serves as a transitional period between the refreshing coolness of spring and the impending heat and humidity of June and July.

In contrast to the next month of June, when summer is in full swing, May in Maryland offers a delightful blend of warmth without the extreme heat, making it an ideal time for outdoor exploration and enjoyment of the state's diverse landscapes.
