Brace for days of higher-than-normal temperatures for this time of year, San Diego. A heat wave will settle in for the Fourth of July holiday week.

"As we head through this week, we are going to be warm for your Fourth of July," NBC 7 Meteorologist Sheena Parveen said. "So, beach weather in the forecast for the coast, temperatures near 80 for the inland valleys, mid-to-upper 80s mid-week and -- we head into the weekend and we get even warmer."

The mountains will experience temperatures in the low-90s to start the week and will approach triple digits by the end, Parveen added.

The deserts will experience the most extreme heat and are under an excessive heat warning, which was extended through 11 p.m. Monday. Dangerously hot conditions will lead to highs between 110 and 118 degrees in the desert, according to the National Weather Service.

Officials advised people in those areas to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors.

Authorities also reminded the public to never leave pets or children inside vehicles on days that are even a little warmer than normal, as locked cars can turn into death traps in mere minutes.

The mercury could reach as high as 119 degrees in the desert by Friday, according to the NWS.

Mostly clear conditions are expected in the inland valley areas with highs reaching the upper 80s, and highs are expected to hit the upper 90s near the foothills.

"Slow warming sets in across inland areas starting on Tuesday, continuing into next weekend. Night and morning low clouds and fog will continue along the coast and far western valleys through much of next week," the NWS reported.

The mountains will also heat up, hitting the low 90s to low 100s throughout the week, with mostly clear and sunny conditions.

Sunday's downtown forecast is for patchy fog before 11 a.m. Otherwise, mostly sunny, with a high near 79 and a north wind from 5 to 10 mph becoming west in the afternoon.

The coast will remain mild through the week, with partly cloudy conditions and highs expected to hit the upper 70s.

Monday's San Diego surf forecast includes a low-risk rip current, with surf height from 1 to 3 feet and a west swell from 280 degrees and south swell from 210 degrees.

"Areas of night and morning low clouds and fog will continue along the coast and far western valleys through the week. No hazardous marine conditions are expected through Thursday," the NWS said.
