Saturday, May 23: Patchy fog and a late-night shower chance for Sheboygan County
Sheboygan County, WI — Saturday, May 23, 2026
Patchy fog and a small late-night shower chance are the main weather notes for Sheboygan County in the National Weather Service’s Saturday morning update, but Memorial Day still looks sunny and warm.
Fog late Saturday night into Sunday morning
For Sheboygan County’s WIZ052 forecast zone, the National Weather Service calls for mostly cloudy skies Saturday, then patchy fog after midnight Saturday night and into Sunday morning. There is also a slight chance of light showers late Saturday night and early Sunday, so drivers should allow extra time if visibility drops before sunrise.
Sunday should turn mostly sunny by the afternoon, with a better setup for outdoor plans once the morning fog lifts.
Nearshore waters could see the same early-morning slowdown
The Milwaukee/Sullivan office’s outlook and the Sheboygan-to-Port Washington nearshore forecast both point to patchy fog on the Lake Michigan waters and a chance of showers before daybreak Sunday. Early boaters should be ready for slower visibility, especially before 7 a.m.
Memorial Day remains the best day of the stretch: sunny skies, light southwest winds, and calm-looking lake conditions with 1- to 2-foot waves. Inland highs reach the lower 80s, with upper 70s near the lake.
For weekend plans, the simple takeaway is to work around the overnight fog and keep a close eye on conditions before sunrise Sunday. After that, the holiday forecast looks friendly for travel, cookouts, and time outside.
