Milwaukee woke up to a surprisingly cool and breezy start on Saturday, July 25, 2026. At Mitchell Field (KMKE), temperatures hovered near 63°F with dew points in the mid‑50s and a southwest wind blowing around 15–17 mph. Skies will be partly sunny, and most of the metro area should stay dry, with afternoon highs topping out near 82°F. If you are heading to the water, beachgoers from north of Port Washington through Sheboygan should keep an eye on the surf and nearshore currents later today as conditions build.
Afternoon Outlook
Those low clouds that slipped in overnight are expected to break up and thin through the morning and early afternoon, allowing temperatures to climb into the low 80s. Southwest winds around 5–10 mph will likely keep any lake breeze pinned close to the shoreline, so inland neighborhoods should warm a bit faster than spots right along the water. There is only a slight chance of an elevated thunderstorm late this afternoon or tonight north of Madison and Milwaukee, and most of the region is expected to stay dry.
Beach Conditions
Later today, a Moderate Swim Risk is in effect for Lake Michigan beaches in Sheboygan County as south to southwest winds kick up 2–3 foot waves. That means more frequent breaking surf and stronger currents. Lifeguards and local officials are urging swimmers to steer clear of piers, breakwalls and river mouths while the risk is in place. Boaters should be prepared for choppy nearshore waters and take extra care when launching or returning to harbor.
Weekend Heat And Storm Threat
By Sunday and Monday, the cool start to the weekend will be a distant memory. Highs jump to near 92°F Sunday and around 91°F Monday. Dew points in the lower to middle 70s will send heat‑index values close to 100°F. On top of the steaminess, there is a potential for stronger thunderstorms, including a window for severe storms, mainly from Sunday afternoon into Monday evening. Exact timing and location are still uncertain. According to the National Weather Service Milwaukee/Sullivan, a Heat Advisory may eventually be needed if the hot, humid pattern holds.
How To Stay Safe
Anyone sensitive to heat should plan to ride out the hottest stretch of the afternoon indoors in air‑conditioned spaces and keep water close at hand for both people and pets. The City of Milwaukee Health Department maintains a list of cooling sites and local resources, and residents can call 2‑1‑1 for assistance. If you do head to the lake, follow instructions from lifeguards and posted swim advisories. When a Moderate Swim Risk is in effect, avoid piers, breakwalls and river mouths where currents can be especially dangerous.
