Tomorrow, on Friday, storms with thunder and lightning are expected during the afternoon.
The likelihood of rain is low, and light precipitation is forecasted. The temperature variation is anticipated to range from a maximum of a tropical 33°C to a minimum of a warm 25°C.
The maximum heat index, which represents the influence of relative humidity on air temperature, is estimated at a dangerously hot 46°C. Take into consideration that the heat index values are calculated for shade and light wind conditions. Bear in mind that direct sunshine exposure increases weather impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees.
This expected maximum temperature is expected to mirror October's typical high of 32.7°C.
Sunrise will be at 05:53 and sunset at 17:43; tomorrow's daylight will last for 11h and 50min.
