What does that mean . For today, 72 at Half Moon Bay to 80 in San Francisco and we have low to mid 80s almost tolerable in richmond and also in oakland, but 87 you can see there in san mateo and then 90s and 100s for the rest of us.

Those steps include setting your air condition to 78 degrees, turning off all the lights you dont need and not using your major appliances.
