The game against Italy was scheduled to take place on June 14 at 2100 local time (2am UK time), but has now been moved to 1800 (11pm).
England had hoped to kick-off at night, but FIFA changed the time following pressure from broadcasters, who were concerned about viewing figures.
Temperatures in Manaus can reach more than 30 degrees centigrade in June and humidity levels soar above 80 per cent in the city, which is located in the middle of the Amazon rainforest.
England manager Roy Hodgson and Club England managing director Adrian Bevington made it clear that they preferred to play at 9pm local time, but FIFA has gone against their wishes.
World football's governing body claim a 6pm kick-off shares "similar conditions" to a 9pm one.
Hodgson admitted he had no control over FIFA's decision following the draw, but stated his preference for a 9pm kick-off.
The England manager said just after being put in Group D: "At the moment the kick-off time is at 9pm and that's what I'm working on.
"We're happy that it's then, of course, but it's out of our hands.
"Our views will be taken into account. How much resistance we can make I really don't know."
Bevington, who was part of the England party in Salvador, said after the draw: "That's something for TV and FIFA and we have no control over it.
"But playing at 9pm in Manaus is clearly helpful from our side and from a football point of view. We can't deny that it's better to play in Manaus later in the day."
