Thanks to Zack Malson for the photo from Sunday’s low tide. Today, hours before the official arrival of summer, low tide will be even lower, so we begin our calendar highlights on the beach:

LOW-LOW TIDE: The tide is out to -1.7 feet at 11:38 am today, so it’s a good day for a late morning/early afternoon beach walk. At Constellation and Lincoln Parks, Seattle Aquarium volunteer beach naturalists will be out 10 am-1:30 pm to answer questions – details here.

7-DAY-A-WEEK SCHEDULE STARTS @ COLMAN POOL: Today is the first non-holiday Monday of the year for Colman Pool, the outdoor saltwater pool on the shore at Lincoln Park, and it marks the start of daily operations through Labor Day. See the full schedule, and other information about the season (including swim-meet-closure dates), by going here.

TALK ABOUT INTERNATIONAL SCHOOLS/DUAL-LANGUAGE IMMERSION: 6 pm at Concord International in South Park, you’re invited to a community meeting to talk about Seattle Public Schools‘ international-education/dual-language-immersion programs – details in our calendar listing. (723 S. Concord)

TINKERLAB DROP-IN: 6-7:30 pm at Delridge Library, all-ages drop-in for STEM-based crafts/activities. Tonight’s theme is “Chain Reaction.” (5423 Delridge Way SW)

QUIZ/TRIVIA NIGHT: Three venues have Monday night quizzes/trivia on our calendar – 7:30 pm at The Skylark in North Delridge, 7:30 pm at Christo’s on Alki, 8 pm at Shadowland in The Junction.

LIVE JAZZ: The Triangular Jazztet performs at 8 pm at Parliament Tavern. No cover. (4210 SW Admiral Way)

SOLSTICE SUNSET WATCH: Tonight’s forecast has clouded up a bit since last we looked, but you never know when the sun might make an appearance after all, so plan to join Alice Enevoldsen at 8:45 pm at Solstice Park to mark the official changing of the seasons (the solstice moment is 3:34 pm our time, but Alice’s sunset watches are always for the sunset closest to the solstice/equinox). More info on her Alice’s Astro Info website. (7400 Fauntleroy Way SW)
