Unprecedented High Temperatures in Nairobi, Kenya
During the early months of 2024, Nairobi, along with other parts of Kenya, witnessed abnormally high temperatures, marking a global trend as reported by the World Meteorological Organization. The year 2023 saw record-breaking high temperatures, with January 2024 emerging as the hottest month globally to date. Gilbert Ouma, a seasoned expert in meteorology from the University of Nairobi, sheds light on this unusual weather pattern.
Anomalous Weather Conditions in Nairobi
Traditionally, Nairobi experiences comfortable average temperatures ranging from 24°C to 25°C in the higher range and 17°C to 18°C in the lower range. However, during the December-January-February period, maximum temperatures typically peak between 26°C and 27°C. This year, temperatures soared to unprecedented levels, reaching between 29°C and 30°C, even hitting 31°C. This surge of approximately 6°C above the norm has significantly impacted the local climate, though the fluctuating nature of the high temperatures prevents the classification of the phenomenon as a sustained heatwave.
Factors Driving the Sudden Heat
The prevailing weather conditions in Kenya can be attributed to the northward flow of winds from December to February, primarily passing through continental regions, including deserts. These wind patterns, characterized by periodic waves, have contributed to the recent heatwave observed across East Africa. The trajectory of these winds plays a crucial role in dictating temperatures in Kenya, with a direct path over landmass resulting in the extreme temperatures experienced earlier in 2024.
Notably, the phenomenon of climate change has led to a steady increase in global average temperatures, setting new records each year. Consequently, the already elevated temperatures witnessed during the December-January-February season may further escalate due to this climatic shift. Additionally, the uncharacteristic heavy rains in December and January, attributed to the delayed el Niño phenomenon, temporarily moderated the soaring temperatures, only for the usual heat to intensify post the rainy spell.
Regional Impact
The repercussions of the scorching temperatures have transcended Kenya, affecting neighboring countries in East Africa. The collective experience of this hot weather anomaly underscores the need for heightened vigilance and adaptation strategies in the face of changing climatic conditions.
