Summer is on the way, and from the sounds of it, we'll be jamming out to live performances. Parks in San Diego County offer a variety of free, live, outdoor concerts during late spring and summer.

Some jam sessions have already started, but there will be a lot more to listen to as the summer heats up.

Balboa Park Twilight Concerts

Spreckels Organ Pavilion's 40-year tradition brings music to the landmark, outdoor organ on Tuesdays, Wednesdays, and Thursdays during the summer. This year, the tunes start on Wednesday, June 21, at 6:30 p.m.

Dinner and a Concert

El Cajon will rock out all summer with this ongoing series at its downtown Prescott Promenade. Shows are Fridays, 6-8 p.m., except for this week when the local act PHT /Patrick Howard Trampus Band takes the stage on Thursday, May 18. Pack food, or visit a nearby restaurant or vendor, and enjoy a picnic with a side of live music.

For 50 years, this series has filled Coronado's air with music. This year, the performances start on Sunday, May 28, and a new act will perform each Sunday evening until Labor Day.

Friday Nights Live

This 4-week series kicks off at Santee Trolley Square this Friday, May 19, with local rock band It's Never 2 L8. The shows run weekly through June 9, then the city's beat continues with Santee Summer Concerts just down the street.

Santee Summer Concerts

This Thursday night series will bring music to Town Center Community Park starting June 15 and concludes with the Aug. 17 show (there's no concert July 6). Bring chairs or a blanket, and if you're hungry, be on the lookout for food trucks on site.

Lake Poway Summer Concert Series

This summer series opens with a soulful show by Blue Breeze Band on Sunday, June 25, at 5:30 p.m. Performances are scheduled each Sunday through Aug. 13 — though there is no show on July 2. Food trucks will also be on site, so all you'll need to bring is a comfortable spot to sit.

University Heights Summer in the Park

Head out to Trolley Barn Farm, 6-8 p.m., for live music by local bands. This year, the shows are every Friday in July and on Aug. 4. Food will be available for purchase nearby, and there will be space for picnicking.

Psst... Some communities are still working on their roster, so more free concert series are likely to be announced.
