What is it with August?

I think it's the heat.

Although re-creation has been tried, no one has been successful: 1969: Woodstock. August 15-18, a farm in New York.

Since 1938, the first full week of August: Sturgis Bike Rally in the South Dakota Black Hills.

Sorta' since 1986, kinda' the last week of August, although it started, according to Wikipedia, as a Solstice event: Burning Man Festival, north of Reno NV in the desert.

The Bayreuth Festival, a 6-week celebration late July through most of August of Richard Wagner's operatic masterpieces. Bayreuth Germany.

I wonder if they draw the same crowds, if it's a decision each year: Sturgis or Wagner... Nevada desert or Germany?
