Californias Great America Memorial Day weekend 2027

29 to 31 May 2027, with the weekends either side. Californias Great America runs busy across the break at 74% on a typical day. The figure is the forecast queue level against the park's own busiest days: 100% is its peak, under 30% is a quiet day.

Memorial Day is Monday 31 May 2027, the traditional start of the summer season.

Californias Great America has not published its hours for these dates yet, so every day is shown; check the park's site before you go. Crowd levels are modelled from this park's own recorded queue times, school and public holidays, day of the week and the weather forecast, and may not always be right. We score every past forecast against what the queues actually did and publish the result in the crowd forecast accuracy ledger.
