Sesame Place San Diego reopened on March 27, 2026, marking a transition to a seasonal schedule that prioritizes spring and summer operations. The park launched its fourth birthday celebration alongside the new schedule, operating daily through early April and then moving to weekends ahead of Memorial Day weekend. Beginning May 22, 2026, water attractions and slides joined the lineup, with the park hosting the Sesame Summer Splash event on select dates from May 23 to September 21, 2026.
This season also carries ongoing legal matters, as Sesame Workshop filed a federal lawsuit against SeaWorld Parks & Entertainment in March 2026, a background development during the park’s operational shift. For visitors, the changes mean a concentrated period of activity with updated attractions and timed events, while the park continues to align its offerings with peak tourist seasons and family weekend visits.
