[technical]I've never thought about it before (or did any research), but I would guess that at the equator there are sort of two *seasons*, each repeated twice a year. At the spring and autumn equinoxes the sun will be passing directly overhead the equator, thus the hottest day(s) of the year. At the summer solstice the sun will be as far north in the sky as any other time during the year, and the winter solstice will have the sun to the southern limit. I would say that these two days would be the *coldest* days of the year.
Therefore two *summers* (peaking at the equinoxes) and two *winters* peaking at the solstices.[/technical]
How's that for some worthless ruminating while I'm on the road?
edit: by the way, I think that the mid-summer (northern hemisphere) days at the North lattitudes and the mid-winter (northern hemisphere reference) days at the Southern lattitudes are much longer (more hours of daylight) than any days at the equator.
