Djibouti’s Climatology and Climate Change
Djibouti, a nation situated in the Horn of Africa and straddling the Bab-el-Mandeb Strait connecting the Red Sea and the Gulf of Aden, is a country characterized by its small size yet remarkable climatic and geographic diversity.

Climatology
Djibouti’s climatic conditions are predominantly arid and tropical, with high temperatures and meager rainfall all year round. The annual average temperature hovers around 27.8 degrees Celsius, while the average annual precipitation amounts to a mere 244.6 millimeters. This climate can be divided into two distinct seasons.
The cool, dry season prevails from October to April, featuring mild temperatures ranging between 22 to 30 degrees Celsius, along with relatively high humidity. On the other hand, the hot, humid season spans from May to September, characterized by scorching temperatures ranging from 30 to 40 degrees Celsius and elevated humidity levels. The wettest months in Djibouti are typically July and August, with an average monthly rainfall of about 30 millimeters.
Several factors influence Djibouti’s climate, including its tropical location, proximity to the Red Sea, and varying elevations. Its tropical positioning ensures direct exposure to sunlight throughout the year, resulting in persistently high temperatures.
Additionally, the country’s location along the Bab-el-Mandeb Strait, a significant maritime route, leads to a moderating influence from the warm waters of the Red Sea and the Gulf of Aden, which helps maintain a somewhat cooler climate compared to neighboring regions. Furthermore, Djibouti’s varying elevations play a vital role in shaping its climate, with higher-altitude areas receiving more rainfall and experiencing cooler temperatures than lower-lying regions.
Climate Change
Djibouti ranks among the world’s most climate-vulnerable countries, already experiencing the detrimental effects of climate change. These effects manifest as heightened temperatures, dwindling rainfall, and rising sea levels.
Average temperatures in Djibouti have surged by approximately 1.5 degrees Celsius since the pre-industrial era, and this upward trend is expected to continue into the future. Concurrently, the country anticipates a future decline in rainfall, with climate models projecting a potential reduction of up to 20% by the close of the 21st century.
Rising sea levels pose a significant threat to Djibouti due to its low-lying coastal areas, which are susceptible to inundation and flooding. Sea levels have already risen by around 20 centimeters since the early 20th century, and this trend is forecasted to accelerate.
Impacts of Climate Change
Djibouti has been grappling with the tangible impacts of climate change. The nation faces more frequent and severe droughts, intensifying food insecurity and water scarcity. These challenges exacerbate existing issues like poverty and unemployment. Specific impacts include:
Food Insecurity
More frequent and severe droughts are making it increasingly challenging for farmers to cultivate crops, leading to food insecurity.
Water Shortages
Climate change has diminished Djibouti’s water resources, making it hard to meet the population’s water needs, resulting in shortages.
Sea Level Rise
Rising sea levels are engulfing coastal regions, displacing residents, damaging infrastructure, and jeopardizing ecosystems.
Extreme Weather Events
Climate change is amplifying the frequency and intensity of extreme weather events like cyclones and floods, causing widespread destruction and loss of life.
Adaptation and Mitigation
The Djiboutian government has taken measures to adapt to and mitigate climate change. It has outlined a National Adaptation Programme of Action (NAPA), which includes initiatives such as improving water management, developing drought-resistant crops, and constructing seawalls to safeguard coastal communities from flooding.
Furthermore, Djibouti is committed to reducing its greenhouse gas emissions, having ratified the Paris Agreement and pledged to cut emissions by 40% by 2030. The government is investing in renewable energy sources such as solar and wind power, and actively promoting energy efficiency measures.
Djibouti finds itself at the forefront of climate change vulnerability. The nation is already grappling with rising temperatures, diminishing rainfall, and sea-level encroachment. The Djiboutian government is taking crucial steps to adapt and mitigate these impacts, yet additional support from the international community is imperative to address this formidable challenge.
