Being that close to the equator, the sun's noon position doesn't shift much through the year. If you're on the equator, the sun is directly overhead on Mar. 21 and Sept. 21, and is lowest on both Dec. 21 and June 21, but it's not much to notice.
Matter of fact, the sun's lowest point of the year on the equator (66.5 degrees altitude on the equinoxes) is about the same as its highest point in Seattle on June 21. So with its constant warmer-than-Seattle-sunshine, it's basically about 80-88 degrees all year long in the tropics and it's shorts time whether it's mid July or waiting for Santa.
