Tomorrow, on Saturday, sunlight and clouds will take turns dominating the sky.
A daytime temperature reaching up to a humid 87.8°F will subtly contrast with a nighttime low of a warm 78.8°F.
The maximum heat index, which combines relative humidity and air temperature, is assessed at a very hot 98.6°F. Note that heat index values are valued for light wind and location in the shade. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees.
The day’s highest temperature is expected to be moderately higher than the standard April average of 82.9°F.
Sunrise will be at 6:04 am and sunset at 6:35 pm; tomorrow's daylight will last for 12h and 31min.
