Temperature Change During Eclipse
If the skies are clear, we can expect a significant drop in temperatures when the eclipse happens.
NASA says, “When sunlight fades at twilight, we always notice how things start to cool down. The same is true for the temporary dimming during a total solar eclipse.”
The graph below shows a 15 degree drop in the temperature during the total eclipse in Lusaka, Zambia, on June 21st in 2001.
