What to do for Summer Solstice in Boston

• Information and image via Harvard Museum of Natural Science

Celebrate the longest day of the year and the official start of summer at the Harvard Museums of Science & Culture's annual Summer Solstice celebration Monday.

That means circus performers, music, dance, food trucks, and hands-on activities for all ages, with free evening admission to the Harvard Semitic Museum, Peabody Museum of Archaeology & Ethnology, and Harvard Museum of Natural History. It's enough to make you forget the muggy weather.

• Here's how long this year's Summer Solstice is, and why we celebrate it

In the spirit of the special day, event attendees can create their own summer crown decorated with seasonal flowers, garden greens or their own "sun streamer with powerful Aztec symbol," according to the museum's event description.

Ben & Jerry's and Bon Me will be on-hand for food and ice cream needs.

The Summer Solstice Celebration is free and open to the public, with free event parking at the 52 Oxford Street Garage. It's about eight minutes from the Harvard Square Red Line T Stop. Divinity Avenue will be closed to traffic during the Solstice.

The event starts at 5 p.m. and runs until the sun sets at 8:24 p.m. A countdown will precede the setting of the sun.

Here's tonight's performance lineup:

5:30 pm
Sudacas
Join us for a lively performance of traditional and pop music from Latin America presented by Marianella Rojas and Esther Rojas. The duo fuses musical elements from their native Colombia and Venezuela with jazz harmony and pop elements to create subtle and fresh sounds. Marianella and Esther met at Berklee College of Music in 2011, and have been playing together ever since.

6:15 pm
Circus Arts Feature Show
Enjoy an engaging performance of circus arts and acrobatics featuring artists from Off the Ground Circus Arts.

7:00 pm
Revels Singers
The Revels Singers—a community chorus directed by George Emlen—will usher in summer with a lively selection of music celebrating the natural world, including ocean-inspired songs and anthems, a paean to the moon, and a stern admonition to be good stewards of the earth, “our only home."

7:40 pm–8:20 pm
Joh Camara and Troupe Sewa
Enjoy a spirited performance of West African drumming that will summon luck and good fortune as we begin the new summer season.

Sidi Mohamed Camara, popularly known as “Joh,” was born in Bamako, Mali in West Africa. Surrounded by great artists and musicians as a child, Joh started traditional dance and drumming at the age of five. Joh resides in Boston, where he teaches traditional Mande culture and language, as well as music and dance traditions from Mali, Guinea, the Ivory Coast, and Senegal
