Despite hopes that the region’s high heat would abate by the weekend, temperatures Sunday started climbing early.
The hot day followed a night that never really cooled down – just the kind of situation that can cause problems for the state’s power grid and put strains on the aging infrastructure that delivers electricity to millions of California homes.
Examples of the hot temperatures include the cities of Livermore, Pleasanton and Fairfield hitting 105 degrees on Saturday.
Sunday is shaping up to be similar, according to NBC Bay Area meteorologist Rob Mayeda.
Mayeda says there will be some relief in the afternoon when a sea breeze coupled with a deepening marine layer moves in.
The beaches up and down the state were expected to be a good 20 degrees cooler than the hottest parts of the valleys.
The continued heat will lead to high demand for energy as people try to keep homes and businesses cool, the non-profit company that manages the state’s energy supply said Sunday.

The California Independent System Operator (Cal ISO) predicted that Californians would use 41,309 megawatts of power during the day. There’s enough energy in the system to meet that demand, the company said, as long as residents conserve.
Conservation on Sunday, while not mandatory, is needed to keep electricity flowing in the state, the system operator said on its website.
