Baltimore receives precipitation throughout the year, with monthly averages ranging from 3 to 5 mm according to climate data. There is no pronounced rainy or dry season based on total volume. The highest amount of moisture, around 5 mm per month, typically falls in July and August. It is slightly drier in January, March, October, and November, which average about 3 mm.

Despite relatively small fluctuations in total volume, the frequency of precipitation in Baltimore changes noticeably with the seasons.

The type of precipitation in Baltimore also depends on the time of year. In summer, when temperatures are high (e.g., July's average high is 30.3°C), it is mostly rain, which can take the form of brief showers. In winter, especially in January (average low -1.2°C) and February (average low 0.3°C), when temperatures drop to or near freezing, precipitation can fall as snow as well as rain. Travelers planning a winter visit should be prepared for this possibility and pack accordingly.

When planning a trip to Baltimore, it's important to consider its changeable weather and four distinct seasons. Layering should be the foundation of your wardrobe, allowing you to easily adapt to temperature shifts throughout the day, especially during the transitional spring and autumn seasons. Regardless of the time of year, comfortable walking shoes are your best friend, as the city is very walkable. In summer (June to August), Baltimore is hot and humid, so opt for light, breathable fabrics. Don't forget sunscreen, a hat, and sunglasses. Given that July and August have up to 15-16 days of precipitation, a light umbrella or compact raincoat will also come in handy.

In winter, from December to February, Baltimore can get quite cold, with January averages dropping to 2.3°C and nighttime frosts being common. You will need a warm jacket or coat, a hat, gloves, and a scarf. Waterproof shoes are a good idea, as precipitation can fall as snow or freezing rain. Spring (March-May) and autumn (September-November) feature moderate temperatures, but the weather can be unpredictable. Layering is especially relevant during these times: bring sweaters, fleece jackets, and a medium-weight coat that can be easily added or removed. An umbrella remains a useful accessory, as rainy days occur during these months too, though less frequently than in summer.
