“It’s not only uncommon for June, but it is rather extreme even in complete terms,” said Daniel Swain, a climate scientist at the UCLA Institute of the Atmosphere and Sustainability, in accordance to NPR. “It would be a pretty intense event for August.” 

The high temperatures have set documents in most sections of the West. The current temperatures are, in some locations, the optimum recorded locally in historical past, when in other locations, they stand for the hottest weeks or months on history.

Which is kind of the vicious cycle of drought and excessive warmth in a warming climate.”
