The coast of Oaxaca lies well within the tropics at a latitude of about 16°. Monthly lows and highs are typically 18° C (64° F) and 45° C (113° F), averaging 30° C (86° F), with little variation from month to month. The region is generally arid along the coast with more rainfall in the nearby mountains. Most guidebooks say that the rainy season runs from May to October, but in recent years, the length of the rainy season has declined so that July to October is more accurate. September is usually the rainiest month. Amounts vary from year to year and most of the rainfall occurs on a relatively few days. Just because it is the rainy season does not mean it will be raining though; it just means it can rain. A typical day in the rainy season would be a clear morning, clouding up in the afternoon, with thunder heard in the nearby mountains. In this hot climate, the afternoon clouds can be quite welcome.

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.
