Riverside and San Bernardino are locked into serious heat today, with the National Weather Service calling for mostly sunny skies and a high near 100°F across the Inland Empire — one of the hottest days of the summer so far. West wind stays light at 0 to 10 mph with gusts up to 20 mph, so it’ll feel like standing in front of a hair dryer. Plan any strenuous outdoor activity for early morning or after sunset, and keep the water bottle full all day.

Today’s Setup

Forecasters at the National Weather Service office in San Diego (SGX) note today’s highs are running 8 to 12 degrees above average, and while a gradual cooling trend kicks in through Tuesday and Wednesday, “average” this week still means the upper 90s. There’s only a slim 3% chance of a stray shower or rumble of thunder, tied to monsoon moisture riding up from Baja California, but any drops that reach the ground will be isolated and light. Overnight lows only dip to around 70, so homes without AC won’t get much relief before sunrise.

Best Window To Be Outside

Get outside before 9 a.m. or after 7 p.m., when temperatures sit closer to the 70s and 80s instead of triple digits. That’s the window for a run through Fairmount Park, an early tee time, or a morning bite out at Lake Perris — fish tend to bite best in the cool hour right around dawn before the heat shuts things down. Bring a fishing hat with neck flap if you’re on the water. If you’re spending real time in direct sun this week, Score a UPF 50+ Sun Hoodie for Just $5 This Fishing Season is worth grabbing before you head out.

Heat And Air Quality

With highs near 100°F and minimal cloud cover, expect the Inland Empire’s typical summer air quality dip during the afternoon peak, roughly noon to 6 p.m. — sensitive groups should limit prolonged outdoor exertion during that stretch. Hydrate before you feel thirsty, and check on elderly neighbors or pets without reliable AC.

Local Games And Events

Catching the Los Angeles Angels host the Houston Astros at Angel Stadium Tuesday, July 28? SGX forecasters expect the cooling trend to still be underway, with midweek temps running around 5 degrees above average — so plan for a hot ballpark and hydrate before first pitch. A Los Angeles Angels jersey or Los Angeles Angels fitted cap earns its keep for sun coverage, and you can Find tickets on StubHub or Get tickets on SeatGeek before gates open. Heading to Greater Palm Springs for the Dancing With The Stars Con at Acrisure Arena on July 31? The ridge is expected to rebuild by then, so bring the same heat mindset — a Dancing with the Stars t-shirt makes a fun souvenir.

Tonight’s Dinner

With triple-digit heat outside, this is peak grilling weather once the sun starts dropping — burgers, steaks, or grilled chicken with corn on the cob cook up fast on a hot grill. An instant-read meat thermometer takes the guesswork out of doneness, and a grill brush and scraper set keeps things clean between courses. For something different, check our smoke tri-tip pellet grill guide. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Monday holds nearly as hot with a sunny high near 99°F, then the gradual cooling trend continues into Tuesday and Wednesday, though SGX still expects temperatures around 5 degrees above average. Forecasters are already watching the upper-level ridge rebuild toward Las Vegas later in the week, with increasing confidence it could bring the hottest temperatures of the summer so far — this heat wave isn’t finished yet.
