Climate: long, hot, humid summers and short, mild to cool winters. A simple fleece pull-over or light coat is good for the winter. A good rain jacket is very nice.
The summers are pretty hot and humid, so short sleeves are pretty important. Shirts like the Serve brand help in the humidity with vented sides.
Bring extra garments (mesh or stretch cotton) because sometimes you end up taking a couple showers a day. The new style garments are game changers.
Elders request black golf pants, as the other colors show sweat marks.

Serve shirts have a ventilation panel in the side of the shirt making them noticeably more breathable. Missionaries serving in hot or humid places absolutely RAVE about this feature. The most popular shirt for hot-climate missions, for sure.
