The Overwatch Summer Games 2020 start date has not been officially announced. Blizzard has been hosting many of the other events this year earlier than usual, but the Summer Games is based on the Summer Olympics. The start and end dates for the event lined up during the last Summer Olympics so players can expect the same thing to happen this year.
Overwatch events are highly anticipated because of the new skins and the addition of new features to the game. As a result, many players are already asking when will the 2020 Overwatch Summer Games event begin?
Overwatch Summer Games 2020 Start Date
Based on past event release dates, the expected release date of the 2020 Overwatch Summer Games event is July 21 and the expected end date is August 11. The event could begin a week earlier, but probably won't start any later than that so the players have less than a month to wait.
Until Blizzard officially announces a release date, nothing is absolutely certain. Many of this year's event like the Overwatch Anniversary were held sooner than in the past so Summer Games could come even sooner.
