Climate for Station: Dar Es Salaam Airpo, Dar es Salaam, Tanzania

The climate profile of Dar Es Salaam Airport reveals a warming trend in high temperatures and a cooling trend in low temperatures over the past decade. However, when considering the all-time data, both highs and lows show a warming trend. Precipitation patterns have become slightly more even, as indicated by a small decrease in the Precipitation Concentration Index.

Coastal Climate Dynamics

Dar Es Salaam Airport, located at -6.867, 39.2, falls under the tropical savanna climate, classified as 'Aw' in the Köppen system. Its proximity to the Indian Ocean significantly influences its climate, contributing to its humid conditions and moderate temperature fluctuations. The coastal geography ensures that the area experiences a maritime influence, which typically moderates extreme temperature variations.

Temperature Trends: A Mixed Picture

Over the past decade, the high temperatures at Dar Es Salaam Airport have shown a warming trend, increasing by 0.16°C (0.29°F). In contrast, the low temperatures have experienced a cooling trend, decreasing by 0.48°C (0.86°F). This divergence highlights a complex local climate dynamic where daytime temperatures rise while nighttime temperatures fall. However, when examining the all-time trends, both high and low temperatures show a warming pattern. Highs have increased by 0.13°C (0.24°F), and lows by a more substantial 0.42°C (0.76°F).

Precipitation Patterns: A Slight Shift

The Precipitation Concentration Index (PCI) for Dar Es Salaam Airport has decreased from a baseline of 16.17 to a current value of 15.73. This slight decrease indicates a more even distribution of rainfall events over time, suggesting that precipitation is becoming less concentrated in fewer, intense events. This shift could be beneficial for agriculture and water management, as it implies more consistent water availability.

Temperature Extremes: Records in Context

The record high temperature at the station is 39.2°C (102.6°F), while the record low is 10.8°C (51.4°F). These extremes provide a perspective on the range of temperatures that can occur in this tropical location. The high temperatures are indicative of the intense heat that can be experienced, particularly during the dry season, while the lows reflect the cooler conditions that can occur at night.

Regional Climate Goals and Implications

Tanzania has been actively working towards climate resilience and adaptation strategies, focusing on sustainable water management and agricultural practices. The slight evening out of precipitation patterns at Dar Es Salaam Airport aligns with these goals, potentially offering more stable conditions for local communities. Recent weather events, such as heavy rainfall and flooding, underscore the importance of understanding and adapting to these climatic shifts.
