Temperatures could slowly become cooler are possible throughout the county for the latter half of next week, according to NWS.
NWS recommends that those working outdoors during this time consider rescheduling outdoor activities and take necessary precautions not to fall victim to heat-related illnesses. The elderly, children and those not used to excessive heat are particularly at risk.
Young children and pets should never be left in vehicles unattended, and that is especially more dangerous during these periods of high heat. Car interiors can reach lethal temperatures in a matter of minutes, NWS said.
The high temps also hit the county as many kids prepare to go back to school.
San Diego Unified School District issued a letter to parents ahead of the beginning of classes, assuring that the district plans to do what they can to keep kids cool:
"You may be aware that warm temperatures are expected next week. Please be assured that our schools will do everything possible to make sure students and staff are safe and comfortable during the school day. All schools have a Hot Weather Plan that will be implemented if needed. You may check with your school for a copy of their Hot Weather Plan or visit the district website for Hot Weather procedures our principal will alert you if excessive heat warrants a minimum-day schedule."
SDUSD asks that parents do their part by dressing children in light, loose fitting clothing and encouraging them to drink water throughout the day.
