Best Time to Visit Skydeck & 360 Chicago: Weather, Time of Day & Sunset

See Skydeck times for your date

The calendar below shows Skydeck's entry times and prices for any date. Both decks sell a set entry time, and the popular ones, sunset and summer weekends especially, go first.

Check your date

Pick the day you plan to go up. Within about a week of today the card shows the National Weather Service forecast for downtown Chicago, visibility first, then cloud cover and the chance of rain; further out it shows the long-run average for that month, and it always says which of the two you are looking at. It also gives the sunset time, each deck's hours and any holiday or event on that date.

Visibility first: cloud, fog and haze

Visibility decides how much you see from either deck. Both sit more than 1,000 feet above the street, so a low layer of cloud can put the deck inside it, and fog or haze can hide the distant views even when the streets below are clear. Rain matters less than the height of the cloud: a day of passing showers can still have clear spells, while a dry day under low overcast can hide the skyline for hours.

Tickets bought directly from the decks are not refunded for poor visibility. Skydeck's terms say all sales are final, and it publishes no weather closures. 360 Chicago says it cannot refund for low visibility or bad weather and stays open in all conditions, but it lets you reschedule a ticket bought directly through its Manage My Booking page before your entry time, sometimes for an extra cost.

The GetYourGuide tickets for both decks can be canceled free up to 24 hours before. After that, bad weather is not a reason for a refund (the 360 Chicago listing says so outright), so look at the forecast before the deadline, and if cloud or poor visibility is forecast and your stay is several days long, move to a clearer day. The public forecast for downtown does not give the height of the cloud base, so on the day itself Skydeck's live webcams are the best check before you set out.

Clear or partly cloudy days are most common from June to September. In NOAA's records for O'Hare, the city's official weather station, July and August each average about 20 clear or partly cloudy days, against about 12 in December and 13 in January. December has the most cloudy days (18.5) and July the fewest (10.1), while August and October have the most fully clear days. Our own count from hourly airport observations between 2015 and 2025 found the cloud base below the height of Skydeck's floor in about one daytime hour in five in January, and in fewer than one in 50 in July and August. Airports are inland, so the lakefront can differ, but the seasonal pattern is the same at O'Hare and Midway.

Day or night: which time is best?

Once the sky is clear, the hour decides which view you get, and because both decks sell tickets for a set entry time, it is a choice you make when you book, whatever month you travel. In daylight you see the street grid, the Chicago River and the lakefront in detail, and on a clear day both operators say you can see four states. Around sunset the western sky over the West Loop changes color and the city lights come on. After dusk the skyline is lit up, which is a different picture again. The hour also shapes the rest of your day: a morning visit leaves the afternoon free for a river cruise or the museums, while a sunset or evening visit fits after a day of sightseeing on the ground.

Skydeck

Skydeck's own advice is to go early in the morning or around sunset: Morning visits typically have shorter lines, while sunset provides stunning views of the city skyline and Lake Michigan. Its visitor tips page puts it as just after opening or after sunset, and asks you to arrive 30 to 45 minutes before sunset if you want to see it. The deck opens at 9 a.m. From March to late May it is open until 10 p.m.; from May 26 to September 30, 2026 it is also open until 10 p.m., opening at 8:30 a.m. on Saturdays; and from October to February it closes at 8 p.m. from Sunday to Friday and 9 p.m. on Saturdays, although Monday to Thursday run to 10 p.m. from January 18 to 28, 2027. Last entry is 30 minutes before closing. The winter hours are the time slots in Skydeck's booking calendar, read on September 25, 2026, and they match last winter's published hours. Some older Skydeck pages list later weekend closing times, so check the calendar for your date.

Most guests spend 45 to 60 minutes at Skydeck, starting in the museum on the lower level before the elevator to the 103rd floor and The Ledge. Skydeck says the visit can take longer at peak times and around sunset.

360 Chicago

360 Chicago keeps the same hours all year: 9 a.m. to 11 p.m. daily, with last entry at 10 p.m. For a quieter visit it recommends noon to 2 p.m., and it notes that it often sells out from Friday to Sunday and on holiday weekends. (Its page for groups gives a wider 9 a.m. to 5 p.m. window.) Most guests spend 45 minutes to an hour on the 94th floor, and there is no time limit, so you can go up before sunset and wait for the lights at CloudBar, the bar on the deck.

Timing a sunset visit

Sunset in Chicago comes at about 4:20 p.m. in mid-December and 8:27 p.m. in mid-June, and the table further down gives every month. 360 Chicago suggests booking at least an hour before sunset, and Skydeck asks you to arrive 30 to 45 minutes before, because the time on your ticket is when you join the queue for the elevators. The date checker above gives both entry times for your day.

For the lit skyline, go up after dusk. In June and July that means after about 9 p.m., which Skydeck's 10 p.m. closing still allows. From December to February it is dark soon after 5 p.m., and once Skydeck's winter last entry has passed, 360 Chicago is the deck still open, until 11 p.m.

How the view changes through the year

Winter (December to February). The sun sets between about 4:20 and 5:40 p.m., so all three views, daylight, sunset and the lit skyline, fit into a late-afternoon visit before dinner. December and January are among the cloudiest months, and snow can cover the city: January averages 11.3 inches at O'Hare. Holidays at Skydeck adds lights and decorations to the museum and the deck from November 13, 2026 to January 4, 2027. Skydeck closes at 8 p.m. (9 p.m. on Saturdays), so a later visit is at 360 Chicago.

Spring (March to May). The clocks go forward on the second Sunday in March, and by mid-April sunset is around 7:30 p.m. Skydeck is open until 10 p.m. again. Cloud is still common in March and April; May has fewer cloudy days, although it is the wettest month of the year.

Summer (June to August). Clear or partly cloudy days are most common in these months and September, and July and August have the fewest cloudy days of the year. Sunset comes after 8 p.m. from mid-May to early August, so the lit skyline means going up after about 9 p.m. Skydeck says evening entry times are popular in summer, at weekends and on holidays. 360 Chicago lists the Navy Pier fireworks, on Wednesday and Saturday nights from Memorial Day to Labor Day, and the Air and Water Show in August among the events you can watch from its deck; the 2027 dates had not been published when we checked.

Fall (September to November). September still has few cloudy days, with sunset around 7 p.m. in mid-month. Cloud increases through October and November. Fall color in the parks below is usually at its best in mid- to late October, according to Morton Arboretum, although it can shift a couple of weeks either way. Skydeck's hours shorten from October 1, and the clocks go back on the first Sunday in November, which moves sunset an hour earlier overnight.

Cloudy days are days when cloud covers at least seven-eighths of the sky between sunrise and sunset, in an average month at O'Hare. High and low are average afternoon highs and overnight lows. Skydeck's winter hours are its booking calendar's time slots; from January 18 to 28, 2027 its Monday-to-Thursday slots also run to 10 p.m. Last entry at Skydeck is 30 minutes before closing; 360 Chicago is open 9 a.m. to 11 p.m. in every month, with last entry at 10 p.m.

Which deck suits your time of day?

Both decks show the same skyline from different sides of downtown. Skydeck is the taller, at 1,353 feet, with The Ledge glass boxes; 360 Chicago, at 1,030 feet on the Magnificent Mile, is open later and has a bar on the deck.

How busy do the decks get?

Neither deck publishes visitor numbers by month; Skydeck's only published figure is about 1.3 million visitors a year. What the operators do say: Skydeck calls evening entry times popular, especially in summer, at weekends and on holidays, and 360 Chicago often sells out from Friday to Sunday and on holiday weekends. Both sell a set number of entries for each time slot, so popular slots sell out.

The nearest monthly guide is travel through Chicago's airports. In 2025 O'Hare and Midway handled about 6.2 million passengers in February against 10.3 million in July. That counts connecting passengers and residents as well as visitors, so treat it as a guide to how busy the city is, not a count at either deck. Skydeck's own booking calendar tells a similar story for the coming months: when we read it on September 24, 2026, most weekdays from November to February had barely sold, while the most-booked dates ahead were the eve of the Magnificent Mile Lights Festival (November 20), Thanksgiving and Friday, December 18.

One change for 2026 and 2027: Choose Chicago, the city's tourism bureau, says 360 Chicago is running a single elevator from September 8, 2026 until the second quarter of 2027, which limits group sizes and the time slots on offer. If a particular time matters to you, book it ahead. To skip part of the wait, Skydeck sells Expedited Entry, an express route to the elevators with its own lane at The Ledge, and 360 Chicago sells a Fast Pass that skips part of the entry line only. Our Skydeck guide covers the waits in more detail.

Choosing your Chicago dates

A deck visit takes about an hour, and most of a Chicago trip happens at street level, so choose your dates for the city as a whole. For a wider Chicago trip, May, June and September offer the best overall balance: afternoons of about 71 to 80°F at O'Hare, the full river-cruise season and plenty of clear or partly cloudy days, without the strongest July and August heat. July and August have the most clear or partly cloudy days for the decks, but afternoons average 83 to 85°F, and July sees the most passengers through the city's airports. October is a good cooler alternative, at about 63°F, although cloud increases through the fall, and January averages 32°F. Some architecture river cruises stop for the winter while others keep running with heated cabins (our architecture tours guide has the details), and museums and both decks are open all year. Whichever month you pick, the decks work: the cloud on the day and the hour you choose shape the visit most, although clear or partly cloudy days are more common in summer and early fall.
