Kicking off with Puerto Vallarta weather in December, this destination in Mexico is known for its pleasant temperatures, making it an ideal vacation spot during the winter months. Puerto Vallarta’s unique microclimate is influenced by its geography, with the Sierra Madre Occidental mountains to the east and the Pacific Ocean to the west, creating a pleasant temperature range throughout the year.
The average high temperature in December is around 77°F (25°C), while the average low temperature is around 61°F (16°C). This temperature difference is one of the factors that contribute to Puerto Vallarta’s relatively pleasant climate during the month of December. In addition to its pleasant temperatures, Puerto Vallarta is also known for its sunshine hours, with an average of 7 hours of direct sunlight per day during December.
Understanding Puerto Vallarta’s Climate and Geography
Puerto Vallarta, a coastal city in the state of Jalisco, Mexico, is known for its unique microclimate that makes it a popular tourist destination during the winter months. The city’s geography plays a significant role in shaping its climate, which is characterized by mild winters and warm summers.
Located on the Pacific coast of Mexico, Puerto Vallarta is nestled in the Bay of Banderas, one of the largest bays in the country. The bay’s influence on the local climate is substantial, as it creates a microclimate that is warmer and drier than the surrounding area. The city’s elevation also contributes to its pleasant climate, as it is situated at an average elevation of 25 meters (82 feet) above sea level. The surrounding mountains, including the Sierra Madre Occidental, help to create a rain shadow effect, resulting in a relatively dry climate.
Puerto Vallarta’s proximity to the Pacific Ocean also plays a crucial role in shaping its climate. The prevailing trade winds bring warm, moist air from the ocean, resulting in a relatively high humidity level throughout the year. However, the city’s location in a valley creates a temperature inversion, where the air closest to the ground is warmer than the air above it. This temperature inversion helps to keep the city’s temperature relatively mild, even during the winter months.
One of the key factors that contribute to Puerto Vallarta’s pleasant temperatures during December is its location within the Intertropical Convergence Zone (ITCZ). The ITCZ is an area near the equator where the trade winds converge, resulting in a region of low pressure and high humidity. During the winter months, the ITCZ shifts northward, bringing warmer and more humid air to Puerto Vallarta.
Another factor that contributes to Puerto Vallarta’s pleasant temperatures is its distance from the cold polar jet stream. The polar jet stream is a fast-moving band of air that flows from the north and brings cold air to the region. Puerto Vallarta’s location south of the polar jet stream helps to protect the city from the harsh winter weather.
| Elevation | Average Elevation (m) |
|---|---|
| Surrounding Mountains | 500-1,500 |
| City Elevation | 25 |
The combination of Puerto Vallarta’s geography, its location within the ITCZ, and its distance from the polar jet stream results in a unique microclimate that is characterized by mild winters and warm summers.
