What precisely is it that creates a monsoon season in Las Vegas?
“The monsoon happens when we have a shift in the winds. They come from the south rather than from the west or the southwest. When they come from the south, that’s able to pull some tropical moisture up,” Florendo stated.

“That high likes to set up shop right over the Four Corners region. It rotates all this moisture from the south up toward us,” Florendo stated.

The raindrops are literally greater than you get with a typical winter storm, Florendo stated.
Hurricanes popping out of the Gulf can truly prolong the monsoon season, which often begins in July and ends in late September.
“If a hurricane hits Mexico and sends a lot of rain — and it has a lot of rain — and it gets caught up in that high, then we’re in trouble,” Florendo stated.
