Our September events calendar features a wide variety of entertainment in the Seattle-Tacoma metropolitan region. As always, we focus on events with a regular adult admission price of $15 or less, or virtual admission of $30.
For more expensive events, we look for popular events with available ticket discounts that can help bring the price down. Occasionally there are higher priced events we feel might be worth a splurge, especially music, film, and arts events that support local entertainers.
We’ll continue to update this calendar throughout the month as organizers announce new events and online content.
