Kicking off with weather in Galapagos December, this topic captures the essence of the islands’ unique climate and weather patterns during this month.
The Galapagos Islands, located off the coast of Ecuador, experience a subtropical climate, influenced by the cold water upwelling from the deep sea. This phenomenon leads to cooler temperatures and lower precipitation levels during December, making it an ideal time for visiting.
Understanding the Galapagos Climate during December
The Galapagos Islands, located off the coast of Ecuador in the Pacific Ocean, experience a unique climate due to their proximity to the equator and the cold Peru current. December is a transitional month in the Galapagos climate, marking the beginning of the dry season. This period is characterized by reduced rainfall and increased temperatures.
The Galapagos Islands, comprising three main islands – Santa Cruz, San Cristobal, and Isabela – exhibit different climate patterns. Santa Cruz, being the most populated island, experiences a slightly more pronounced temperature fluctuation throughout the year. San Cristobal, on the other hand, tends to be warmer and sunnier, while Isabela, the largest island, showcases a more varied climate due to its diverse geography.
Temperature Fluctuations
Santa Cruz Island experiences temperatures ranging from 23°C (73°F) at night to 29°C (84°F) during the day. San Cristobal Island is usually a degree or two warmer, with temperatures spanning from 22°C (72°F) to 30°C (86°F). Isabela Island exhibits the most significant temperature variation, with lows around 20°C (68°F) and highs reaching 30°C (86°F).
Precipitation Patterns, Weather in galapagos december
December marks the beginning of the dry season, characterized by reduced rainfall across the Galapagos Islands. However, the precipitation patterns vary between the islands. Santa Cruz Island typically receives around 80mm (3.1 in) of rainfall in December, while San Cristobal Island receives approximately 70mm (2.75 in). Isabela Island, due to its diverse terrain and geography, experiences the most varied precipitation pattern, with some areas receiving significantly more rainfall than others.
Ecosystem Impact
The seasonal climate fluctuations in the Galapagos Islands have a profound impact on the local ecosystem. The dry season, which begins in December, brings an increase in sunlight and temperature, favoring the growth of certain plant species. On the other hand, the reduced rainfall can lead to water scarcity, affecting various animal species that rely on these resources. The varying climate patterns between the islands also contribute to the unique biodiversity of the Galapagos, making it a fascinating subject for scientific study and conservation efforts.
Weather Conditions in Galapagos during December – An In-Depth Analysis

The Galapagos Islands experience a unique and diverse climate, influenced by their geographical location near the equator and the cold Humboldt Current. December is part of the southern-hemisphere summer, characterized by warm temperatures and increased humidity.

Cold Water Upwelling and December Weather
The cold water upwelling off the coast of Galapagos is a critical factor in shaping the region’s climate. During December, this phenomenon intensifies, leading to cooler water temperatures and increased marine productivity. As a result, the ocean’s surface temperature drops, ranging from 62°F (17°C) to 68°F (20°C), which in turn affects the weather patterns. The upwelling creates a zone of high atmospheric pressure, which promotes the formation of high-pressure systems, often bringing clear skies and light winds.
Cold water upwelling is a critical component of the Galapagos’ unique climate, influencing temperature, precipitation, and marine life.
In addition, the Galapagos cold water upwelling plays a crucial role in regulating the local ecosystem, supporting an incredible array of marine life, including an abundance of marine birds, fish, and mammals. The upwelling’s influence on the region’s climate and ecosystem is a vital aspect of understanding the region’s complex and delicate balance.
The upwelling also has a significant impact on the precipitation patterns in Galapagos during December. While the average precipitation is relatively low, the upwelling creates an area of high humidity near the coast, often resulting in occasional rain showers or light drizzle. These precipitation events can help maintain the region’s lush vegetation and ensure the water supply for the local wildlife.
This analysis highlights the significance of cold water upwelling in shaping the climate and ecosystem of Galapagos during December.
Wildlife Activities and Weather in Galapagos during December: Weather In Galapagos December

The Galapagos Islands are home to an incredible array of unique and endemic species, many of which are adapted to the archipelago’s distinct climate and weather patterns. During December, the weather in the Galapagos remains pleasant, with temperatures ranging from the mid-70s to mid-80s Fahrenheit (23-30°C), making it an ideal time for wildlife activities and exploration.
As the warm waters of the Pacific Ocean bring with them an abundance of nutrients, marine animals such as sea lions, penguins, and marine iguanas are drawn to the shores of the Galapagos. However, the changing weather conditions in December affect the behavior and habitat of these marine animals in various ways.
- The sea lions, for example, tend to congregate on rocky shores and islands during this time, often competing for space and resources. As the waves and tides become stronger, they have to adapt their behavior to avoid being swept away by the powerful currents.
- Penguins, meanwhile, take advantage of the cooler waters and more abundant food sources to thrive during this period. Their populations tend to increase, and they can often be seen waddling around the islands, tending to their young and foraging for fish and squid.
- Marine iguanas, on the other hand, rely heavily on the sea currents to bring them food. During strong currents, they are forced to seek shelter in areas with calmer waters, where they can feed on the lush algae that grows on the rocks.
