Wrigley Field hosts one of the best rivalries in the NL Central on Monday night — Cubs vs. Brewers, 6:40 PM CDT — and the National Weather Service is flagging rain and wind for the Chicago area around game time. Come prepared, because this is Wrigley in May, and the Windy City will make you feel it.

Game Weather Bottom Line

Rain and wind are the story for Monday’s game. The forecast pattern moving through Chicago this week features south winds at 10 to 15 mph with gusts capable of reaching 25 to 30 mph, along with a meaningful chance of showers — conditions that can linger into evening hours at an open-air ballpark like Wrigley. Check an updated forecast Monday afternoon before you leave home, especially if you’re heading to the bleachers.

Rain Delay And Wind Risk

The south wind setup rolling through the area this weekend carries shower and thunderstorm chances that can push well into the evening. Wrigley Field has no roof, and the ivy walls don’t stop a stiff breeze from reminding you this is Chicago. If showers arrive before first pitch, the good news is that squalls tend to move quickly through the lake corridor — but a delay is genuinely possible, and late-game precipitation risk is worth planning around. Monitor radar Monday afternoon and keep the MLB app handy for any official delay updates.

What To Wear And Bring

Start the evening in a Chicago Cubs t-shirt and layer up. A Chicago Cubs jersey worn over a long sleeve is a practical move — it keeps you warm as temperatures drop after sunset and still shows out for the rivalry. May nights at Wrigley cool off fast once the sun is gone, and that south wind makes it feel sharper than the thermometer reads.

For rain, a stadium rain poncho is the practical call — compact, Wrigley-bag-policy friendly, and ready to deploy in seconds when the sky decides to act up. Pair it with a waterproof stadium bag to protect your phone, wallet, and anything else that can’t get soaked. A stadium blanket earns its weight in the upper deck or during a delay, when sitting still in damp air gets cold fast.

Top it with a Chicago Cubs fitted cap — dual duty for team colors and keeping rain off your face. If you’re arriving early enough to catch afternoon sun, toss a sunscreen stick SPF 50 in your bag before you go. And if you’ve got bleacher seats, bring a baseball glove: Wrigley’s short porches on a rivalry night mean home runs and foul balls come into the crowd more often than you’d think.

Tailgating And Arrival Window

Wrigleyville before a Cubs-Brewers game has a different kind of buzz — half celebration, half argument, all baseball. Target a 5:00 PM arrival if you want a seat at any bar on Clark or Addison. Brewers fans travel, and they show up loud. The neighborhood fills fast on rivalry nights.

Watch Monday’s radar from about 3 PM onward. If showers push through in the late afternoon, there’s a reasonable chance of a dry window at first pitch before conditions deteriorate later in the game. Either way, factor in extra time — Wrigleyville street parking fills up early, and CTA Red Line drop-off at Addison is your most reliable option regardless of the weather.

If you still need seats, Get tickets on SeatGeek or Find tickets on StubHub — rivalry matchups between these clubs move quickly, and last-minute inventory can still surface good value, but don’t wait long. The Cubs are 28-16 at home and riding a win streak. The Brewers come in at 24-17 on the road, also with a win streak. Both teams have something to prove in the NL Central, which means this game has real weight behind it.

Want to show up right? A Chicago Cubs jersey or Chicago Cubs t-shirt gets you game-ready and, on a rainy night, keeps the gear practical and the colors loud.

Monday night at Wrigley, under the lights, Cubs and Brewers — a little rain just makes it more memorable.
