A Fathers Day weekend heat wave for the Inland area will get worse, with temperatures expected to climb a few degrees each day before peaking Wednesday, with a forecast high of 103 to 111 degrees, the National Weather Service said.

A high-pressure system centered over Arizona will push temperatures 12 to 18 degrees above average for this time of year for the Riverside and San Bernardino valley areas.

A heat advisory is in effect until 9 p.m. Wednesday for much of the Inland area.

Excessive heat warnings will last through 9 p.m. Thursday, June 22 for the San Gorgonio Pass, which is expected to hit 114 to 122 degrees through Wednesday, and the High Desert of San Bernardino County, where highs will range from 107 to 115 degrees during the same period.

The Weather Service is expecting some records to be set early next week. Palm Springs could tie or break its all-time record of 123 degrees on Wednesday, said James Brotherton, a San Diego-based National Weather Service meteorologist.

“This is definitely exceptionally hot for many areas, especially the length of the heat wave, almost a week of excessive temperatures,” said Brotherton. “It’s kind of to the point where you don’t want to be outside if you can help it.”

Cooling is expected to begin Thursday, June 22, with Inland temperatures dropping to the low-to-high 90s by Saturday, June 24.

Brotherton said heat exhaustion and heat stroke — which can be fatal — are both possible risks, especially to the elderly, children and those with medical conditions. People should check on their elderly neighbors and remind them to turn on their air conditioners before it gets too hot, he said.

People who have to be outside are urged to wear lightweight and loose-fitting clothes, drinking plenty of water and taking more frequent breaks inside or at least in the shade.

Some residents found a respite from the heat Sunday at The Cove Waterpark in Jurupa Valley.

Austin Grissom took his wife and 6-year-old twins to swim the pool, play in the lagoon and float down a river.

“It’s a fantastic way to cool off,” said Grissom, a 49-year-old Eastvale resident.

Grissom said he likes the heat because it means more summer trips to the beach, water park, the Colorado River and other places with his kids.

“We’re water people,” he said. “Hot weather is necessary for all these activities.”

Fred Rodriguez of Rialto was wading in the lagoon with his girlfriend and 7-year-old son, Daniel.

“It feels good to me,” said Rodriguez, 45. “I’m from Chicago originally. I’d rather be too hot than too cold.”

Rodriguez said he appreciated the fact that The Cove was less crowded than other water parks and didn’t have lines for rides.

“It’s nice and relaxing,” he said.

Jose Lomeli, who lives in the La Sierra area of Riverside, said the weather mattered less than enjoying Father’s Day with his three kids, ages 6, 9 and 12. After enjoying the day at the water park, the family planned to have dinner at The Cheesecake Factory.

“We love it,” said Lomeli, 35. “We’ve been looking forward to it since last week. It helped out that it was super hot. It’s a two for one.”
