Temperatures will climb from 34°C on Sunday and Monday to 38°C by Wednesday, with tropical nights where minimums stay above 20°C.

Day-by-day progression
Sunday and Monday will be warm with highs around 34°C and lows of 16-19°C. The ITU will reach 80 units both days. Skies will be mostly clear, and wind will be light to moderate.
On Tuesday, the heatwave begins. Maximum temperatures will rise to 35-36°C, and the night will be tropical with a low around 20°C, though peri-urban areas may drop to 17°C. The ITU will exceed 80 units, and the sky will be variable, clearer at night and in the morning.
