The 2026 crowd model, in numbers
Most “best time” guides stop at general advice. These figures come straight from the Parks Radar crowd model, which scores every operating day of 2026 for SeaWorld San Diego against the park’s own typical attendance, not against other parks. A crowd index near 100% is a packed, near-capacity day; the lower the number, the shorter the lines. SeaWorld San Diego is projected to operate 365 days in 2026.
