NOAA normals for Las Vegas, what the enclosed, air-conditioned A's ballpark means for fans, and what to bring for the hot walk from the bridges and garages.
Quick answer: Las Vegas is hot for most of the baseball season, with NOAA normal highs above 99°F in June, July and August. The A's ballpark is reported to be fully enclosed and air-conditioned, so the heat is mostly about the walk in. Bring water for the walk, sun protection, your phone and ID, and a light layer for the AC.
How Hot Is Las Vegas During Baseball Season?
Very. These are the official NOAA 1991-2020 monthly normals for Harry Reid International Airport (station USW00023169), the standard reference for Las Vegas weather:
- March: average high 71.1°F, average low 50.5°F
- April: average high 78.5°F, average low 56.9°F
- May: average high 88.5°F, average low 66.1°F
- June: average high 99.4°F, average low 75.8°F
- July: average high 104.5°F, average low 82.0°F
- August: average high 102.8°F, average low 80.6°F
- September: average high 94.9°F, average low 72.4°F
Two things stand out. First, the middle of the season is triple digits on a normal day, not just a bad one. Second, summer nights barely cool off. A normal July low of 82°F means a night game does not fix the heat on its own. If you are walking to a 7 p.m. first pitch in July, it will still feel like summer outside.
Will It Be Hot Inside the Ballpark?
It should not be. The Las Vegas Review-Journal reported in June 2026 that the ballpark will be fully enclosed and climate-controlled, with air conditioning delivered from under the seats. The team's own ballpark site, ballparkexperience.athletics.com, describes the building as climate-controlled. That is the big difference between this park and an open-air stadium in a hot city: once you are inside, the plan is for you to be in a cooled space.
We do not know yet what temperature the building will be kept at, how it will feel in different sections, or how the large glass window the team has described affects things on a sunny afternoon. Those are questions for Opening Day 2028, not now.
What About the Walk to the Gates?
This is where the heat matters. The ballpark sits on the former Tropicana site at Las Vegas Boulevard and Tropicana Avenue, confirmed by the team. According to the Review-Journal, the main entrance is an elevated plaza tied into the pedestrian bridges at that intersection, and existing bridges connect Excalibur and MGM Grand to the corner. The Review-Journal also reported that the ballpark will rely on parking at nearby MGM Resorts properties, plus on-site garages.
Put together, most fans will spend some time outdoors: crossing bridges, walking from a resort garage, or waiting at a rideshare pickup. Walking times from specific resorts have not been published, so plan for the outdoor part of your trip to take longer than you expect, especially with a crowd. For the parking picture, see our parking guide.
How Should You Handle Hydration and Sun?
Quick answer: Las Vegas is hot for most of the baseball season, with NOAA normal highs above 99°F in June, July and August.
- Drink water before you leave. Start hydrated rather than trying to catch up once you arrive.
- Carry water for the walk. Whether you can bring a bottle into the ballpark is part of the bag and item policy, which has not been announced. Plan to finish it or check the policy once it is published.
- Cover up for day games. Sunscreen, a hat and sunglasses make the outdoor stretch easier in the afternoon.
- Do not rush. Walking fast across a bridge in 100°F heat is how people end up feeling sick before first pitch. Leave earlier instead.
- Watch kids and older fans. They feel heat faster. Build in shade and rest stops inside the resorts along the way.
What Should You Bring to an A's Game in Las Vegas?
Until the team publishes an official list, keep it simple and stick to things you would want at any ballpark:
- Your phone, charged. Many venues use mobile tickets, and you will want it for rideshare or finding your group. Confirm how your tickets are delivered when you buy.
- Photo ID. Useful for anything age-restricted and generally smart in Las Vegas.
- A light layer. After a hot walk, a cooled building can feel chilly, especially if you are sitting still for three hours. A thin long-sleeve or light jacket you can tie around your waist works.
- Sun gear for the outside part. Hat, sunscreen and sunglasses.
- Water for the walk. See the note above about the unannounced item policy.
Leave the big backpack at the hotel until the bag policy is out. Many large venues limit bag sizes, but we are not going to guess what the A's will allow.
Is a Spring or Fall Game Different?
Yes, at least outside. NOAA normals put average highs in the 70s in March and April and in the high 80s by May, with evenings cooler. September still averages near 95°F. Early season and late season games will usually mean an easier walk in, but bring the same light layer, because the building is still climate-controlled.
What Is Still Unknown
- The ballpark bag policy, including size limits and whether sealed water bottles are allowed. Not announced yet.
- Gate opening times. Not announced yet.
- The indoor temperature target and whether any areas are open to the outside air. Not announced yet.
- Shade, misters or cooling stations on the walking routes and bridges. Not announced yet.
- Walking times from nearby resorts and garages. Not published.
- The first game date. The team has confirmed only "Opening Day 2028."
We will update this page when the team publishes policies. For everything else about planning a trip, start at our Plan Your Trip hub, and if this is your first game, read the first-timer's game day guide.

Not entirely. The NOAA normal low in July is 82°F, so the walk to a summer night game will still be hot. The cooling relief is inside the enclosed ballpark, not outside.
What is the bag policy at the A's Las Vegas ballpark?
It has not been announced. Until the team publishes it, leave large bags at your hotel and do not count on bringing a water bottle inside, though you should carry water for the walk.
What should I bring to an A's game in Las Vegas?
A charged phone for mobile tickets and rideshare, photo ID, sun protection for the outdoor walk, water for the walk in, and a light layer for sitting in the air-conditioned seats.
