View this series of photos that illustrate the Seasonal Change in Huatulco from dry season to rainy season.
The rainy season is also hurricane season, and hurricanes offshore can have a strong impact on the amount of rainfall. Refer to the satellite, radar, and storm map images below.
November through April is the dry season. As things dry out, most plants (that are not watered) in the lower elevations lose their leaves, but the bougainvillea, which grows wild, takes this opportunity to bloom, and star fruit trees produce their fruit. The terrain is hilly along the coast with granite outcroppings extending into the sea against the backdrop of the Sierra Madre del Sur to the north. Venturing into the mountains, you will soon find yourself in the jungle with a corresponding drop in temperatures as the elevation increases. In the dry season when things are pretty brown on the coast, mountain areas may still be green due to rainfall at the higher elevations. The change in elevation permits a wide diversity of crops including coffee in the moderate elevations and mushrooms in the high elevations.
Fog is extremely rare on the coast of Oaxaca, but has occurred. See photos.
