San Antonio is waking up to patchy fog on Monday, June 1, with afternoon highs climbing to near 89°F once skies partly clear — if you have outdoor plans early today, hold off until around 10 AM CT when that fog lifts and the day opens up.

Today’s Setup

The National Weather Service says areas of fog — some spots dropping to as little as a quarter-mile visibility — are hanging over the eastern half of the metro through mid-morning. By 10 AM CT, expect partly sunny skies to take over, a high near 89°F, and a light ESE breeze around 5 mph. Rain chances today are just 4%, so the River Walk, the Alamo, and Brackenridge Park are all in great shape from mid-morning onward. Tonight stays warm with a low near 75°F and partly cloudy skies — classic early-June San Antonio.

Best Window To Be Outside

Once that fog burns off around 10 AM CT, Monday is the cleanest outdoor window of your week. A morning walk along the River Walk or a round at one of the Hill Country courses will be comfortable before the heat peaks in early afternoon. Keep an insulated water jug 1 gallon on hand — the National Weather Service notes moisture is already building with southerly Gulf flow pushing PWATs above 1.5 inches, so 89°F will feel stickier than it reads.

What To Wear Or Bring

Light, breathable clothes and sunscreen are the call today. If the kids are home, a kiddie splash pad in the backyard is a smart afternoon option when the heat peaks. Planning a float trip down the Guadalupe River later this week? Check out the 2-Person Intex Float with Built-In Cooler for $24 — a solid deal for the warm weeks ahead.

NBA Finals Game 1: Spurs Host the Knicks Wednesday

The biggest event in the Alamo City this week: the San Antonio Spurs host the New York Knicks in NBA Finals Game 1 on Wednesday, June 3 at Frost Bank Center. The arena is indoors, so no weather worries once you’re inside — but Wednesday brings a 33% chance of showers and storms, mainly afternoon and evening, as the National Weather Service kicks off an active stretch through the weekend. Give yourself extra time heading downtown. Wear your San Antonio Spurs jersey for the home opener, or pack a San Antonio Spurs hoodie for the arena AC. Still hunting for seats? Get tickets on SeatGeek before they’re gone.

Dinner Tonight

With warm, humid air settling in, keep it light — pasta or a quick stir-fry means minimal oven time. Father’s Day is right around the corner, and once storms clear out later this week, a Father’s Day grilling set is worth having ready for the weekend. Love low-and-slow? Check out how to smoke tri-tip like brisket for an easy weekend cook. Need ingredients tonight? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Tuesday warms to near 91°F under mostly sunny skies, but a slight chance of showers and thunderstorms arrives Tuesday evening — the National Weather Service flags roughly 7 PM to 1 AM CT as the window to watch, particularly over the northern part of the area. Wednesday through Saturday stays active with daily rain and storm chances as Gulf moisture builds. The primary hazard is locally heavy, tropical-style downpours — San Antonio’s Flash Flood Alley lives up to its name in these setups, so keep a close eye on low-water crossings near Leon Creek and along the River Walk if heavy cells move through. Check outdoor gear deals to stay prepped for the wet week ahead.
