Having never lived near the equator, it's only today that I theorized that although summer and winter are astronomically-speaking indistinguishable at latitude zero, these seasons receive different sun exposure than spring-fall.
The midday sun on the equator is vertical twice a year at the equinoxes. On the tropics, the midday sun is vertical once a year, at the summer solstice. For other locations between the tropics, I'm guessing it also happens twice a year sometime between the summer solstice and the nearest equinoxes.
Now, I'm curious about actual climate differences between December and June at specific regions on the equator.
