Washington, DC is baking under sunny skies today with a high near 100°F and a heat index climbing to 107 — the National Weather Service says the smart move is to knock out errands, dog walks, or workouts before 9 AM or after 7 PM and treat midday as an indoors-only window.

Today’s Setup

It’s sunny and scorching, with a southwest wind at 5 to 9 mph (gusts to 18 mph) doing little to cut the humidity. Forecasters give only a slight, 20% chance of a shower or thunderstorm after 3 PM, mainly where a bay/river breeze runs into a surface trough stretching from DC northeast toward Baltimore. Tonight stays muggy with a low around 78 and heat index near 105, with any storm chance fading by 11 PM.

Best Window To Be Outside

Early morning along the Potomac River or the National Mall is your best bet before the pavement heats up. If you’re headed to Nationals Park, day games will feel brutal — bring a portable misting fan and an insulated water jug 1 gallon so you’re not relying on concession lines to stay hydrated.

Rain, Wind, Fire, Or Heat Risk

Heat, not rain, is the headline. The NWS forecast discussion says today marks the start of a near record-breaking heat wave, and DC could challenge its all-time record of four straight 100-degree days depending on how hot it gets today and Saturday. Thursday’s forecast high of 103°F (heat index to 110) and Friday both look like near-locks for triple digits, with DCA and BWI in range of daily record highs Thursday through Saturday. Beyond the heat, the NWS notes thunderstorm and severe-storm chances increase through the Independence Day weekend as the heat dome breaks down. The Weather Prediction Center’s excessive rainfall outlook isn’t flagging the DC area today — its watch areas are the Upper Midwest and southeast Florida.

What To Wear Or Bring

Light, breathable clothing, sunscreen, and a refillable bottle are non-negotiable. If weekend storms knock out power, the DARAN 288Wh Power Station is a smart $90 backup worth grabbing now while it’s discounted for Prime members.

Gameday & Weekend Events

The Washington Nationals host the Pittsburgh Pirates July 3 and July 4 at Nationals Park — expect sweaty tailgates, so pack a cooler and grab a Washington Nationals jersey or Washington Nationals fitted cap before first pitch. Across town, Washington Spirit face Houston Dash at Audi Field on July 3. Music fans should watch for the Louis Tomlinson concert at The Anthem on July 7 — Get tickets on SeatGeek and grab a Louis Tomlinson t-shirt — while Madison Beer plays The Anthem July 6 (Madison Beer t-shirt).

Dinner Tonight

It’s too hot to fire up the stove. Go with a cold Thai noodle salad, a build-your-own wrap bar, or smoothie bowls blended in a high-powered blender and served in an insulated tumbler 30oz to stay cold on the porch. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Thursday climbs to 103°F and stays sunny, Friday holds near triple digits with rising storm chances, and Saturday’s high near 100 could tie DC’s record heat streak — all while severe thunderstorm risk builds into the Fourth of July weekend. Check back as the holiday forecast firms up.
