Ukraine, co-hosts of Euro 2012 with Poland, face England in the eastern city of Donetsk at 19:45 UK time in a match they have to win to qualify for the quarter-finals.
The last match played in Donetsk between Ukraine and France on Friday was halted for 55 minutes due to a thunderstorm and a huge downpour which drowned the pitch at the Donbass Arena (pictured).
France won 2-0 after the Group D match resumed.
"The situation in Donetsk is good, unlike the last match. Temperatures will not be too high - about 25-27 C (77-80 Fahrenheit) and then falling," said Mykola Kulbida, head of the Ukrainian meteorological centre.
For Sweden's simultaneous game with France in the capital Kiev, Kulbida foresaw a little rain and thunder but said this would be over before the match starts.
