The climate-adjusted World Cup predictor

Start with the actual Opta supercomputer odds for the 2026 finals. Then layer in what the models leave out: stadium heat, the travel grind across three countries, and weather disruption. Watch who the climate quietly moves up, and who it moves down.

The climate dials — move them
Climate impact intensity 0 = pure Opta odds · higher = climate matters more 1.5
Heat & humidity50%
Travel load30%
Weather disruption20%

The three weights are rebalanced to total 100% automatically. Heat is split into how hot a team's venues run and how well the squad tolerates it, so warm nations take a smaller hit than cool-climate sides at the same exposure.

What the climate changes

Same favourites. Different podium.

At default settings the climate layer does not crown an outsider, it re-sorts the contenders. The cool-climate European sides give ground. The warm nations and the heat-trained hosts gain it.

The climate profile behind each team

Why the model moves them

Four inputs per side, on a 0–100 scale. Venue heat is how hot their scheduled stadiums and kick-off slots run. Heat tolerance is squad and home-climate adaptation. Travel and weather are the logistical and disruption load.

How the model works, and what it assumes ▾
This is a thought-experiment model, not a betting tool. It takes published Opta odds as the football baseline and applies a transparent climate adjustment. Venue heat and travel inputs are modelled estimates grounded in the sources below, not FIFA's confirmed per-group stadium schedule. Every dial is yours to move.

The maths

Each team carries a climate-stress score built from three parts:

  • Heat disadvantage = venue heat exposure × (1 − heat tolerance). A hot schedule hurts a cool-climate squad far more than a warm-nation one.
  • Travel disadvantage = total travel load across the group and likely knockout path.
  • Weather disadvantage = exposure to storms, humidity swings and stoppage risk.

Those combine using your three weights into a single score S. Each team's Opta probability is multiplied by e^(−k × S), where k is the intensity dial, then everything is renormalised to 100%. At k = 0 you get the pure Opta odds back.

Baseline odds (Opta supercomputer, 25,000 sims)

Spain 16.1%, France 13.0%, England 11.2%, Argentina 10.4%, Portugal 7.0%, Brazil 6.6%, Germany 5.1%, Netherlands 3.6%, Norway 3.5%, USA 1.2%, Mexico ~1.0%.

Climate evidence

  • Venue heat exposure is read directly from Bloomberg's per-team chart of heat stress across each side's three group games (2016–2025 conditions, FIFPRO thresholds). Exposure blends each team's average and peak WBGT, so air-conditioned games (the 63.7°F floor) genuinely lower the burden. This matters: France, Brazil and Norway get zero air-conditioned games and run hot in all three, while Spain, England, Germany, Argentina, Portugal and the Netherlands each get two air-conditioned games for recovery despite a higher peak. The per-team air-conditioned game count is shown on each profile card. Peak readings: Netherlands ~87°F, Germany ~86°F, England ~85°F. Coolest draws: Spain ~71°F, Mexico ~73°F.
  • 14 of 16 host cities are likely to exceed the 28°C WBGT extreme-heat threshold in a typical summer. Houston, Miami, Dallas, Monterrey and Atlanta run hottest; Vancouver, Seattle, Toronto and Denver run coolest. Air conditioning or retractable roofs at Dallas, Houston, Atlanta, LA and Vancouver.
  • Late-afternoon and early-evening matches in Miami and Kansas City carry a 30%+ risk of WBGT above 28°C, rising past 50% in a hotter-than-average summer.
  • Heat, cross-country travel and disrupted sleep are flagged by performance scientists as challenges that could rival the opposition.
  • The final projects ~88°F WBGT, the hottest final heat stress since 1994.
