What Happened

The synoptic progression for the week followed a regular late winter pattern. Some anomalies were present in the sense that both the South Atlantic and the southern Indian high pressure cells showed abnormally strong core readings, but at the same time, both slipped southward as the week progressed, diminishing their direct impact on the continent.

Local weather was characterised by the large differences in nighttime temperatures between the southern, central and northern regions. Windy conditions reigned for the entire week across the whole country. Noticeable was the difference in wind direction. In the south, the wind blew mostly from west to east and in the north from east to west. This is a clear signal of the transition from winter to summer.

Conditions in Namibia’s southern half were still directly impacted by the South Atlantic high while further north, the strength of the anti-cyclonic circulation is growing by the day bringing in tropical air from Zambia and Angola. In Windhoek, more or less at the centre of the zone where these opposing systems meet, the to and fro is seen in the cool nights with a southerly to south-easterly wind direction, versus the warm afternoons, which is a combination of warmer air flowing in from the north-east, and later in the afternoon aided by diabatic compression as the airmass sinks due to upper air high pressure control.

This see-saw weather phase will continue until the South Atlantic high consistently keeps to its customary position at about 33°S, or even further south, and until its core pressure subsides to 1024 mB. In the meantime, abrupt alternating intrusions of cold from the south and warmth from the north, will also continue.

Two more features, very much at play during the week, are the inferred cloud base and relative humidity. When the cloud base is high, i.e. above 16,000 feet, humidity plunges to less than 10% and local barometric pressure reads between 1024 and 1020 mB. As the stance reverses during the day, the pressure drops to below 1020 mB and humidity quickly shoots up to between 15 and 20%. At the same time, the cloud base sinks to around 12,000 feet. This is the most reliable indication of the daily interplay between opposing southern and northern systems.

By the end of the week, the South Atlantic high’s core has shifted far south, straddling the 40°S latitude but with enormous strength, reading about 1036 mB. The southern Indian high is also displaced to the south, but with a somewhat weaker core at 1028 mB. Only a weak remnant of the continental high was still in situ over the South African interior.

What’s Coming

The visual shows the outlook for precipitation for the five days starting this Friday, 24 August. As expected, there is no rainfall on the charts for Namibia but the biggest contribution to the accumulated rainfall for the Western Cape will come from a strong frontal system that will make landfall during Saturday and last through Sunday into Monday.

The South African Weather Service has issued warnings for the Western Cape for heavy rainfall and even “disruptive’ snow on the mountains forming the south-western curve of the escarpment.

In Namibia, the expectation is for very windy conditions in the south during Saturday, followed by a cold night, and a cool Sunday. In the north, conditions will remain warm to hot, with the first vestiges of spring present in Bwabwata and the Zambezi.

From Sunday to Monday, the migrating high will ridge in from South Africa via Botswana with considerably colder conditions in the Karasburg district, the areas along the Gemsbok Park border and in the Kalahari along the Botswana border.

This will result in a substantial pressure differential between Namibia’s east and its west with very windy conditions along the escarpment later on Monday and into Tuesday.

Conditions will normalise during Tuesday night and by Wednesday it should be a warm to hot early summer day with light wind from the north.

Following reverse listing, public can now acquire shareholding in Paratus Namibia


20 February 2020, Windhoek, Namibia: Paratus Namibia Holdings (PNH) was founded as Nimbus Infrastructure Limited (“Nimbus”), Namibia’s first Capital Pool Company listed on the Namibian Stock Exchange (“NSX”).

Although targeting an initial capital raising of N$300 million, Nimbus nonetheless managed to secure funding to the value of N$98 million through its CPC listing. With a mandate to invest in ICT infrastructure in sub-Sahara Africa, it concluded management agreements with financial partner Cirrus and technology partner, Paratus Telecommunications (Pty) Ltd (“Paratus Namibia”).

Paratus Namibia Managing Director, Andrew Hall

Its first investment was placed in Paratus Namibia, a fully licensed communications operator in Namibia under regulation of the Communications Regulatory Authority of Namibia (CRAN). Nimbus has since been able to increase its capital asset base to close to N$500 million over the past two years.

In order to streamline further investment and to avoid duplicating potential ICT projects in the market between Nimbus and Paratus Namibia, it was decided to consolidate the operations.

Publishing various circulars to shareholders, Nimbus took up a 100% shareholding stake in Paratus Namibia in 2019 and proceeded to apply to have its name changed to Paratus Namibia Holdings with a consolidated board structure to ensure streamlined operations between the capital holdings and the operational arm of the business.

This transaction was approved by the Competitions Commission as well as CRAN, following all the relevant regulatory approvals as well as the necessary requirements in terms of corporate governance structures.

Paratus Namibia has evolved as a fully comprehensive communications operator in Namibia and operates as the head office of the Paratus Group in Africa. Paratus has established a pan-African footprint with operations in six African countries, being: Angola, Botswana, Mozambique, Namibia, South Africa and Zambia.

The group has achieved many successes over the years of which more recently includes the building of the Trans-Kalahari Fibre (TKF) project, which connects from the West Africa Cable System (WACS) eastward through Namibia to Botswana and onward to Johannesburg. The TKF also extends northward through Zambia to connect to Dar es Salaam in Tanzania, which made Paratus the first operator to connect the west and east coast of Africa under one Autonomous System Number (ASN).

This means that Paratus is now “exporting” internet capacity to landlocked countries such as Zambia, Botswana, the DRC with more countries to be targeted, and through its extensive African network, Paratus is well-positioned to expand the network even further into emerging ICT territories.

PNH as a fully-listed entity on the NSX, is therefore now the 100% shareholder of Paratus Namibia thereby becoming a public company. PNH is ready to invest in the future of the ICT environment in Namibia. The public is therefore invited and welcome to acquire shares in Paratus Namibia Holdings by speaking to a local stockbroker registered with the NSX. The future is bright, and the opportunities are endless.
