We're only into the month of June but, so far, the Golden State is experiencing its hottest year on record.

The National Climatic Data Center finds that between January and May, temperatures in California were five degrees warmer than the 20th century average. 

"This bested the previous warmest January through May for California that happened in 1934. So we broke a long-standing record for the state," climate scientist Jake Crough said. 

Crough says several cities are breaking record temperatures.

The cities of Los Angeles, San Diego, Sacramento, San Francisco and Fresno have all had their warmest year on record this year, Crough said. 

The impact of the record heat is the drought.  

The good news is that Crough is forecasting an 80 percent chance of an El Nino this winter, which would bring wetter than normal conditions.
