La Liga president Javier Tebas said: “We have worked with the historical (average for time of year) temperatures and with the 15-day forecast.”
Both numbers can be seen alongside each game in the fixture list on La Liga’s web page.
The kick-off time causing most concern is the 1 p.m. (1100 GMT) slot.
Tebas said: “We have seen that on the weekend of June 12 the weather is going to be cool. So, we have programmed games at 1 p.m.
“If the weather changes and the temperature rises, we will move the game to a 5 p.m. slot.
“The 1 p.m. slot is important for our partners (clients) abroad.”
