Map of the Day: Los Angeles' Hot Zones

Notice that all of the San Fernando Valley is covered except Studio City and Toluca Lake. Other parts of the city that fall into the hot zone are on the Eastside and South LA | Map via Dept. of Water & Power

This map shows summer average daily temperatures for the microclimates of the City of Los Angeles and was performed by the Department of Atmospheric Sciences at UCLA. The two temperature zones were based on average temperatures less (orange) or greater (red) than 80 degrees.

Based on this map, on Tuesday LA Board of Water and Power Commissioners approved a new rate restructuring plan that would charge customers who use more electricity higher rates, according to the Daily News. But for customers who fall into the hot zones, their power usage can be more before being charged higher rates.

The proposal breaks down billing into three rate tiers that will only go into effect during the hottest months -- from June through September. The majority of Los Angeles homes (58%) fall into the lowest tier, therefore paying the lowest rates. 36% fall into Tier 2 and 6%, people who use three times more electricity than the average user, will be charged the highest rates in Tier 3, which ends up being 5 cents more per kilowatt hour than the lowest rate.
