THE Khomas region is experiencing its worst drought in 90 years, according to official rainfall figures released by the Namibia Meteorological Service this week.
The region received less than a third of its normal quantity of rainfall over the past rainy season from October last year to the end of April this year. The bulk of the north-central regions of the country received about a third of their normal seasonal rainfall, and most of the Erongo, Otjozondjupa and Omaheke regions recorded less than 40% of their normal rainfall totals, figures released by the weather service show.
The Meteorological Service also reported that while the eastern parts of the Zambezi region received between 60% and 80% of their normal seasonal rainfall totals during the 2018/19 rainy season, the situation was worse in the western parts of the region, which has ended up experiencing its worst drought in the last 59 years.
At the weather service’s head office in Windhoek, 106,7 millimetres of rain was measured during the past rainy season – the lowest annual figure since 1929/30, when a seasonal total of 97 mm was recorded at the same spot.
The past rainy season has also been drier in Windhoek than during the 1981/82 season, when a total of 126,2 mm of rain was recorded at the Windhoek Met Office during a severe drought that had Namibia in its grips.
Windhoek’s total rainfall during a normal rainy season is around 355 mm.

The failed rainy season is also reflected in the levels of the main dams supplying water to Windhoek. On Monday, the Von Bach and Swakoppoort dams were storing a combined 29 million cubic metres of water – compared to about 55 million cubic metres a year ago, and more than 62 million cubic metres at the same stage in 2017.
According to the City of Windhoek, city residents again failed to meet water saving targets over the past week. While the city has set a weekly water consumption target of no more than 465 000 cubic metres, actual consumption recorded over the past week was 497 332 cubic metres of water.
Water restrictions in the city are set to be tightened from the start of July.
