Judging from the geographical and weather conditions, it seems that the South American zone is very supportive for national teams from Europe, many national teams seems not comfortable when Qatar as the host of FIFA World Cup 2022 because have hot weather and changed several league schedule for World Cup matches held on at the end year.
Still not official confirmed yet with FIFA World Cup 2026 :Canada/Mexico/United States will held on middle years after several European League competition ended or FIFA keep try begin like the same previous FIFA World Cup 2022 Qatar, but most effective with FIFA World Cup start after all league ended around June until July not on December like in Qatar.
To be honest, I didn't hear any complaints from the participants who competed in the 2022 world cup in Qatar regarding the weather conditions. because, the organizers have designed it in such a way for the convenience of the players. plus, visitors. they've worked around this with state-of-the-art "giant air conditioning" cooling technology to keep the stadium cool. so, weather problems were not an obstacle at the 2022 world cup in Qatar. but regarding the World Cup schedule being changed, that's true. it aims, in order to overcome the extreme climate. As a result, the league schedule was disrupted. but yes, at least the 2022 world cup was successful and lively despite the many controversies surrounding it.
For the 2026 world cup, it's natural that there is no official confirmation yet. because, this event still has a gap of 3 years in the future. at least, before everything is confirmed, the host will make sure in advance to prepare for this once every 4 yearly event. So, yeah, just wait.
