Weather in Lima Peru in December sets the stage for this enthralling narrative, offering readers a glimpse into a story that is rich in detail and brimming with originality from the outset. December marks the start of winter in Lima, Peru, with the temperature gradually decreasing throughout the month.
The weather in Lima, Peru during December is influenced by the El Niño-Southern Oscillation (ENSO), a complex climate pattern that affects the Pacific region. Two climate-related studies have shown that ENSO has a significant impact on the temperature and precipitation patterns in Lima during December.
Weather Patterns in December Lima Peru: Understanding the Regional Impact of the Southern Oscillation
Understanding the climate patterns in Lima, Peru, especially during December, requires an examination of the regional impact of the El Niño-Southern Oscillation (ENSO). This natural climate phenomenon significantly influences the country’s weather conditions, with varying effects in different regions.
The ENSO is an irregular fluctuation between the warm (El Niño) and cool (La Niña) phases of the ocean surface temperature in the eastern Pacific Ocean. It plays a crucial role in shaping the climate patterns in Peru, particularly during the Southern Hemisphere’s summer months (December to February).
The Role of ENSO in Lima’s December Weather, Weather in lima peru in december
During the month of December, Lima’s weather patterns are generally influenced by the ENSO. Research suggests that the city experiences a drier and warmer climate when it is in the midst of an El Niño event, with temperatures occasionally rising to above 26°C (79°F) and average sea surface temperatures between 22-23°C (72-73°F). In contrast, La Niña events tend to bring slightly cooler temperatures and higher precipitation in the region.
A 2019 study published in the Journal of Climate, titled “Impact of El Niño and La Niña on the Climate of Peru,” by researchers from the University of Lima, found that El Niño events led to significant temperature anomalies, with the most pronounced effects observed in the southern regions of the Peruvian coast. Conversely, La Niña events produced more pronounced temperature and precipitation variability in the northern regions of the country.
Comparison of Typical Weather Conditions in Normal and El Niño Years
To better understand the implications of ENSO on Lima’s December weather, let us compare the typical climate conditions in normal and El Niño years.
| Normal Year (La Niña) | El Niño Year |
|-|-|
| Average Temperature: 24°C (75.2°F) | Average Temperature: 26°C (78.8°F) |
| Average Sea Level Pressure (Pa): 987 | Average Sea Level Pressure (Pa): 973 |
| Precipitation: 18.3 mm (0.72 in) | Precipitation: 4.5 mm (0.18 in) |
| Wind Speed: 11.3 km/h (7 mph) | Wind Speed: 12.5 km/h (7.8 mph) |
As seen from the table, El Niño years tend to have higher temperatures, lower sea level pressures, reduced precipitation, and increased wind speeds compared to normal years. These conditions make El Niño years particularly prone to heatwaves.
Historical Occurrence of Extreme Weather Events in Lima
The effects of ENSO have been observed in various extreme weather events that have affected Lima in recent decades. For instance, the 1982-83 El Niño event resulted in severe droughts and heatwaves in the region, causing widespread crop failures and increased mortality rates due to dehydration and other related health issues. In contrast, La Niña events have led to more frequent rainstorms and floods in the region.
The 2017 El Niño event, which affected the southern region of Peru, led to devastating floods that displaced thousands of people. The impact of the 2019 La Niña event caused significant droughts and water shortages, prompting severe restrictions on water usage.
The ENSO has consistently demonstrated its influence on Lima’s climate, particularly during El Niño events. The extreme weather conditions it produces pose serious challenges to the region’s ecosystems, water resources, and food production sectors, underscoring the need for continued research and preparedness efforts to mitigate these effects.

In comparison to Lima, Cancun, Mexico, experiences warmer temperatures and more significant precipitation in December. Phuket, Thailand, and Colombo, Sri Lanka, both have much higher precipitation levels and warmer temperatures than Lima. These regional differences in climate can be attributed to various factors such as the Intertropical Convergence Zone (ITCZ) and the prevailing wind patterns.
Regional and International Weather Phenomena Affecting Climate Conditions
The climate conditions in these cities are influenced by regional and international weather phenomena. According to a study by the National Oceanic and Atmospheric Administration (NOAA), the ENSO (El Niño-Southern Oscillation) can impact weather patterns in these regions. In December, Lima and other Pacific nations are often affected by La Niña conditions, which bring below-average precipitation and cooler temperatures. In contrast, Phuket and Colombo are located in areas influenced by the Intertropical Convergence Zone (ITCZ), which can bring heavy rainfall and warmer temperatures during the monsoon season.
Environmental Impact of Climate Variability on Phuket, Thailand
Phuket, Thailand, is one of the countries most affected by climate change due to rising sea levels and increased storm frequency. According to a report by the Asian Development Bank, Phuket’s beaches and infrastructure are threatened by sea level rise, which could lead to the loss of tourist revenue and local livelihoods. The report highlights the importance of implementing climate-resilient infrastructure and sustainable tourism practices to mitigate the effects of climate change in Phuket and other vulnerable island nations.
According to the IPCC (Intergovernmental Panel on Climate Change), the global average temperature is projected to rise by 1.5°C above pre-industrial levels by 2050, which will have significant impacts on climate patterns and sea levels worldwide.
Historical Climate Trends and Predictions for Lima
Lima, the capital city of Peru, is facing significant climate-related challenges due to its geographical location and climate.
