The climate of Salina Cruz is tropical, hot all year round, with a dry period from December to April and a muggy, rainy period from June to October.
The city is located in the extreme south of Mexico, in the state of Oaxaca. Due to the low latitude (we are at the 16th parallel), the city is hot and sunny even in the middle of winter, however it is windy, because the north wind is channeled between the mountains. Furthermore, the city is particularly hot because the prevailing wind comes down from the hills to the north, producing a foehn-type effect.
From June to November (but with a higher probability from August to October), there is the risk of hurricanes . However, they are generally not violent because we are just north of the area where they are formed, and therefore they are found in their early stages. However, occasionally they can bring heavy rain, as happened with tropical depression Hermine in September 2010.
The average temperature of the coldest month (January) is of 26.3 °C (79 °F), that of the warmest month (May) is of 29.9 °C (86 °F). Here are the average temperatures.
