Atlanta woke up to clear skies Monday morning, May 18, 2026, with temperatures sitting in the mid-60s at Hartsfield-Jackson and nearby stations. From there, the city is set for a quick warmup into the upper 80s, with muggy air turning the afternoon into that classic sticky Southern heat. Southeast winds will run a steady 5 to 10 mph, with occasional gusts near 20 mph on exposed bridges and higher roads. Overnight, temperatures slide back into the mid-60s.
Afternoon Heat And Gusts
NWS Peachtree City calls for highs near 88°F across metro Atlanta this afternoon, with southeast winds of 5 to 10 mph and gusts that could reach 20 mph. Hourly trends point to temperatures climbing into the mid to upper 80s through the afternoon, so outdoor plans later today may feel hotter than the thermometer suggests. Hydrate, grab some shade when you can, and do your pets a favor by keeping them out of the direct sun during the hottest part of the day.
Midweek Storm Chances
Rain chances begin to creep up by Wednesday, May 20, with a 30% chance of afternoon showers and storms, then jump higher Thursday and Friday when showers and thunderstorms become likely. The best shot at more organized showers is along and north of I-20 later in the week, with locally heavy downpours possible in any stronger storm. If you have midweek outdoor plans, it is worth checking in on forecast updates late Tuesday into Wednesday in case the timing shifts.
What This Means For Your Commute
Gusty southeast winds this afternoon could leave high-profile vehicles and cyclists feeling a bit wobbly in crosswinds, especially on bridges and open stretches of roadway. The combination of afternoon heat and sticky humidity may also make midday runs, dog walks, or yard work feel like a grind, so try to knock out the strenuous stuff in the morning or later in the evening when it is cooler. By midweek, a quick look at radar before you roll out is a smart move, since storms may bring brief heavy rain and minor delays on surface streets.
