Humidity Levels in August in Boston
In August, Boston experiences varying levels of humidity, which can greatly influence the daily weather conditions. The two main factors to consider when discussing humidity are the average relative humidity and the dew point. Let’s take a closer look at both of these aspects.
Average Relative Humidity
The average relative humidity in Boston during August ranges from around 65% to 80%. Relative humidity is a measure of how much moisture is in the air compared to the maximum amount it can hold at a given temperature. It is expressed as a percentage, with higher percentages indicating more moisture in the air.
During the summer months, including August, Boston’s relative humidity tends to be on the higher side. This means that the air feels more humid and can have a noticeable impact on how comfortable it is outside. When the relative humidity is high, the air feels heavier, making it harder for sweat to evaporate from our skin, which can lead to a feeling of stickiness and discomfort.
It’s important to note that high humidity levels can also make the air feel hotter than it actually is. This is because our bodies rely on the evaporation of sweat to cool down, and when the air is already saturated with moisture, sweat evaporates at a slower rate, making it harder for our bodies to cool down efficiently.
Dew Point
The dew point is another important measure of humidity that influences how we perceive the weather in August. It represents the temperature at which the air becomes saturated with moisture, causing dew to form. The higher the dew point, the more moisture is present in the air.
In Boston during August, the dew point typically ranges from the low 60s to the mid-70s°F (around 16-24°C). When the dew point is high, it indicates a larger amount of moisture in the air, which can make the weather feel more oppressive and uncomfortable.
When the dew point and the actual temperature are close together, it can create a muggy and sticky feeling. This is because the air is close to its saturation point, and sweat evaporates at a slower rate. On the other hand, when the dew point is significantly lower than the temperature, the air feels drier and more pleasant.
Understanding the dew point can help us better prepare for the weather conditions in August. For example, if the dew point is high, it’s a good idea to dress in lightweight and breathable clothing that allows for better air circulation and evaporation of sweat.
In summary, August in Boston presents varying levels of humidity that can greatly impact how we experience the weather. The average relative humidity hovers between 65% and 80%, indicating a generally humid atmosphere. Additionally, the dew point ranges from the low 60s to the mid-70s°F, influencing the level of comfort we feel in the air. By being mindful of these humidity factors, we can better prepare ourselves and make the most of the beautiful summer days in Boston.

August in Boston brings a mix of weather patterns, including thunderstorms and lightning, as well as fog and mist. These natural phenomena add an element of excitement and mystique to the city’s summer atmosphere. Let’s take a closer look at what you can expect during this time of year.

Thunderstorms are a common occurrence in Boston during August. They are often accompanied by flashes of lightning that illuminate the sky and fill the air with a sense of electricity. These storms can bring heavy rain, gusty winds, and even hail. While they may disrupt outdoor plans temporarily, they also provide a refreshing break from the summer heat.
During a thunderstorm, it’s important to take precautions to stay safe. If you’re outdoors, seek shelter in a sturdy building or a car with a metal roof. Avoid open areas, tall trees, and bodies of water. Lightning can strike from a distance, so it’s crucial to stay away from metal objects and avoid using electrical appliances.
Fog and Mist
Along with thunderstorms, fog and mist can also be a part of the weather patterns in August in Boston. These atmospheric conditions create a mystical ambiance, especially in the early morning or late evening hours. The city’s proximity to the Atlantic Ocean contributes to the formation of fog, as the cooler ocean air interacts with the warm land air.
Fog can sometimes be dense, reducing visibility on the roads. If you’re driving in foggy conditions, it’s important to slow down, use your headlights, and maintain a safe distance from other vehicles. Pedestrians should also take caution and wear reflective clothing to ensure they are visible to drivers.
Mist, on the other hand, is a lighter form of moisture in the air. It can create a delicate sheen on surfaces and give the surroundings a dreamy appearance. Embrace the ethereal beauty of misty mornings by taking a stroll in a park or along the Charles River. It’s a great opportunity to capture stunning photographs or simply enjoy the serene atmosphere.
In summary, August in Boston brings a dynamic mix of weather patterns. Thunderstorms and lightning add a dramatic touch to the summer days, while fog and mist create an enchanting allure. Embrace the unpredictability of these weather phenomena and make the most of your time in this vibrant city.
