Labor Day is just a month away, signaling the dwindling days of summer, the evaporation of vacation time and the inevitable slog up to the holiday season -- which these days starts sometime in October. So while summer is still with us, here's a few ways to enjoy the season in Westport this weekend:

A trove of treasures to tantalize every taste. That's what organizers of a giant tag sale at the Unitarian Church of Westport promise for the two-day shop-a-thon beginning at 10 a.m. Friday. The sale continues until 3 p.m., with the same schedule Saturday at the church, 10 Lyons Plains Road. Early-bird shoppers get a first look at the goods on offer at 9:30 a.m. Friday -- but it'll cost $10 for first dibs. For more information, call 203-227-7205.

On Friday evening, there's a Music on the River benefit for the Westport Historical Society featuring Suzanne Sheridan & Friends, covering standards by Joni Mitchell and Leonard Cohen. The event gets under way at 5:30 p.m. at the HSBC bank building, 19 Post Road East. There's a $10 fee, which includes drinks and hors d'oeuvres on the roof. Call 203-222-1424 or check www.westporthistory.org.

Take time Saturday to make "Summer Nature Discoveries" at Earthplace, the nature preserve and environmental center at 10 Woodside Lane. The 2:30 p.m. program led by naturalist Margaret Ardwin takes place outside if weather permits and indoors if not (and the forecast, alas, in not encouraging). In any case, it's a natural way to combine fun and learning about flora and fauna. Programs are free for Earthplace members; non-member fees are $7 for adults and children over 12, $5 for children 1 to 12 years old and senior citizens. For details, call 203-227-7253 or visit www.earthplace.org.

It's a relatively quiet summer weekend in town, a good time for a relaxing Sunday afternoon taking in the art exhibits on display at the Westport Public Library, 20 Jesup Road. "Look at Me! Kids in Portrait" features portraits by artists Elaine Clayton and Kim Travagliato, alongside a collection of pre-schoolers' self-portraits. "Color/Texture" is a showcase of photographs taken by Guy Sherman in Westport and points far beyond, including Hawaii. The library is open from 1 to 5 p.m. Sundays; call 203-291-4800 or check www.westportlibrary.org.

Mellow out at weekend's end with smooth jazz guitar music, performed by Gene Bertoncini at the Levitt Pavilion. The free performance starts at 7 p.m. at the outdoor venue, 40 Jesup Road. For more details, check http://levittpavilion.com.
