In general, the weather will be comfortable for World Cup play on Monday; but with four different games in separate cities across Brazil, there is one exception.
Play in Recife will begin at 4:00 p.m. EDT with a temperature of around 80 F (27 C) as Croatia takes on Mexico. Humidity will make it feel more like 85-90 F (29-32 C), and heat stoppages could be used if the referees feel the conditions warrant a break for the players. There could also be a stray shower around. The remaining three games will be held in considerably more comfortable weather.
The other game scheduled for 4:00 p.m. EDT will be played in Brasilia, where a temperature around 75 F (24 C) and low humidity will greet players. Plenty of clouds will be around in the morning, but sunshine should prevail by the time Cameroon takes on Brazil in the afternoon.
Play in Sao Paulo will begin at 12:00 p.m. EDT as the Netherlands face Chile. Temperatures at the start of the game will be around 73 F (23 C), then rise to near 77 F (25 C) by the time the game is over. There will be more clouds than sun around, but no threat for rain.
More clouds than sun will also be found in Curitiba, where Australia will take on Spain. Play is scheduled to begin at 12:00 p.m. EDT with a game time temperature of 64 F (18 C) rising to around 70 F (21 C) by the time play is over. There is no threat of rain in Curitiba, but this will be the coolest game of Monday's bunch.
