Hodgson's side face Italy in their opening Group D game at the Arena Amazonia, where humidity levels can hit over 95 per cent.
The Three Lions boss is on a fact-finding mission in Manaus in preparation for the tournament.
With England also due to face Uruguay in Sao Paulo and Costa Rica in Belo Horizonte, the 66-year-old has already been dreaming of winning the competition.
"We football people, I suppose we deal to some extent in dreams," Hodgson told Sky Sports. "It would be foolish I think if you were too pragmatic or too bogged down by the reality of the situation.
"When you put your head down on the pillow at night, you image your team getting the greater success, playing very well and coming back as heroes otherwise it would become a very, very boring exercise.
"It's hot here, but the World Cups are played during the summer. It was hot in South Africa, it was very hot in the USA in 1994, it will be hot here too, but this is something that happens."
With workers still putting the finishing touches to the 42,000-capacity stadium, FIFA are due to announce whether Curitiba in southern Brazil will stay in the tournament.
If not, eight teams - including holders Spain - could have to have their schedule altered, but Hodgson says if that did happen, it would not cause any major disruptions.
"If you were forced into a last minute change, I'm pretty sure it won't cause any major disruptions," he added. "But I hope Curitiba, like all the other stadiums will be ready in time."
