Thick Haze and High Humidity Blanket New England

A thick haze is over Boston Wednesday, as seen by Ed Hughes from the air.

Today, we are experiencing exceptionally high dew points across New England, with values ranging from 75 to 80 degrees. This level of humidity is nearly as high as it gets in this region and is contributing to the thick haze observed over the area. Ed Hughes, piloting his helicopter above Boston, captured a striking photo of this haze, which he submitted via the Noyes’ 1DegreeOutside Weather app.

What is Haze and Why Does It Form?

Haze is a visible layer of particles and pollutants in the air that reduces visibility and gives the sky a milky or grayish appearance. It forms more readily in humid air because moisture in the air can condense around tiny particles, such as dust, pollen, and pollutants, making them more prominent and widespread.

Exceptional Humidity Levels

The current dew points of 75 to 80 degrees are extraordinarily high for Boston and New England. Typically, dew points in this region range from 55 to 65 degrees during the summer, with 70 degrees being considered very humid. Today’s levels are pushing the boundaries of what we usually experience, making the air feel oppressive and sticky.

Impact on Temperatures and Heat Index

With high temperatures reaching the 90s today, the combination of heat and humidity is creating a dangerous heat index around and over 100 degrees in some areas. The heat index, or “feels like” temperature, accounts for both temperature and humidity to reflect how hot it feels to the human body. High humidity impairs the body’s ability to cool itself through sweating, making it feel significantly hotter than the actual air temperature.

Air Quality and Its Relation to Humidity and Haze

The degraded air quality to a moderate level adds to the discomfort and, for some, health risks. High humidity levels can trap pollutants close to the ground, leading to increased concentrations of ozone and particulate matter. This results in poorer air quality, which can affect people with respiratory issues, the elderly, and young children more severely than others.

Suggested Actions for Us All

1. Stay Hydrated: Drink plenty of water to help your body stay cool and function properly.
2. Limit Outdoor Activities: Avoid strenuous activities during the peak heat hours, typically from late morning to early evening.
3. Stay Indoors: If possible, stay indoors in air-conditioned environments to avoid exposure to heat and poor air quality.
4. Use Fans and Air Conditioners: Utilize fans and air conditioners to circulate air and reduce indoor humidity levels.
5. Monitor Air Quality: Keep an eye on air quality reports and limit exposure to outdoor air if the air quality is poor.
6. Check on Vulnerable Individuals: Pay extra attention to children, the elderly, and those with preexisting health conditions, as they are more susceptible to heat and poor air quality.
