The 2026 World Cup is played in June and July, the height of summer in North America, but the weather will vary enormously between the 16 host cities. Miami will be hot and humid, Vancouver will be mild and pleasant, and Mexico City will be warm by day and cool at night thanks to its altitude. Players and fans both need to prepare for the conditions. This guide explains what to expect in each host city and how to pack for a tournament played across a continent.

The hot and humid cities: Miami, Houston, Dallas, Atlanta

The southern host cities will be the hottest at the tournament. Miami, Houston, Dallas and Atlanta can all reach the mid-30s Celsius in June and July, with high humidity that makes it feel even hotter. Afternoon matches in these cities will be physically demanding for players, and fans should expect to sweat. Drink water constantly, wear light clothing and a hat, and use sunscreen. Stadiums in these cities have roofs or shade, but the walk to and from the venue can be brutal. Evening matches are far more comfortable.

The desert and dry heat: Monterrey and Guadalajara

Mexico's host cities bring a different kind of heat. Monterrey is hot and dry, with temperatures in the mid-30s, while Guadalajara is slightly milder. The dry air means sweat evaporates quickly, which can hide how much fluid you are losing, so keep drinking even if you do not feel thirsty. Mexico City, at over 2,200 metres above sea level, is the exception: daytime temperatures are pleasant, around the low 20s, but evenings can be cool and rain is common in the summer months. Pack a light jacket for the Azteca at night.

The mild north: Vancouver, Toronto, Seattle, Boston

The northern host cities are the most comfortable for fans. Vancouver and Seattle have mild summers, with daytime temperatures in the low to mid-20s and cool evenings. Toronto is warmer but rarely extreme, and Boston is pleasant in June, warming up in July. These are the cities where you will want a light jacket for evening games. Rain is possible in Vancouver and Seattle, so pack a waterproof layer. For players, these cities are the kindest on the body, and teams based in the north may recover better between games.

The variable middle: New York, Philadelphia, Los Angeles, San Francisco

The remaining host cities sit somewhere in the middle. New York and Philadelphia can be hot and humid in July, with sudden thunderstorms that cool the air quickly. Los Angeles is warm and dry, with cool evenings, while the San Francisco Bay Area is famously unpredictable: it can be sunny and warm in Santa Clara but foggy and cool just a few miles away. Kansas City is hot in summer, with thunderstorms a regular feature. The lesson is simple: check the forecast the day before each match, and never trust a single day's weather to repeat.

How weather affects the football

Heat and humidity slow the game down, force more water breaks and favour teams that are used to the conditions. Coaches will rotate their squads more in hot cities, and the tempo of afternoon games will be noticeably lower than evening games. Altitude matters too: Mexico City's thin air can leave visiting players breathless, while the home team is used to it. Rain can make pitches slick and fast, which suits quick passing teams. Smart fans will follow the weather as closely as the team news, because conditions can change a match.

What to pack: a checklist for every climate

Pack light, breathable clothing for the day, a waterproof jacket for sudden rain, and a light layer for cool evenings in the north and in Mexico City. Sunscreen, a hat and sunglasses are essential in the south, and a reusable water bottle will save money and keep you hydrated. Comfortable walking shoes matter more than style: you will walk a lot around stadiums and fan zones. Finally, pack a small bag that meets stadium bag policies, so you can carry your essentials without being turned away at the gate.
