Recent Developments

This week’s visual has been chosen from a range of similar charts to show the extent and impact of the South Atlantic High Pressure cell, the single most important dominant force in Namibia’s weather.

For the duration of the week, the same daily pattern was replicated from early morning to early evening. At sunrise, the skies were mainly clear with only some alto level cirrus-nimbus clouds, again showing more of a late winter / early summer pattern than the expected mid-summer stance.

As every day progressed, humidity at surface level decreased, indicating rising air, while the temperature quickly reached 30°C across the entire country above the escarpment. At this stage, usually by about noon, some cloud build-up has started slowly drifting to the south-west from its source in the north and north-east.

By late afternoon, some good cloud cover was observed but the really intense clouds were only present over the Ohangwena, Okavango West, Otjozondjupa and Omaheke regions. Cloud development also followed a regular daily pattern, becoming more visible on satellite images as the day progressed.

The moisture would slowly condensate in a broad band from the Okavango, southwestward, first moving into Otjozondjupa and then into Khomas until it reached the escarpment on the other side of the Hochland. From there it deflected due south, running for about 400 km before it was repelled by the outer rim of the South Atlantic high as it moved in over the southern Namib. On its final leg, the clouds moved back inland crossing central Hardap and into the Karasburg district.

Most noticeable was the promising look of rain every afternoon which eventually fizzled out during the first half of the night, with very little, if any, convection. This is very easy to observe: No convection, no lightning.

The visual provides an easy-to-read format showing that the South Atlantic high carried out its customary mid-summer trajectory, slowly creeping around the continent from west to east and then moving up the Mozambican Channel and ridging back over South Africa’s Limpopo Province, southern Mozambique and Zimbabwe’s lowveld.

The visual also clearly shows the area of lower pressure over the west-central parts of the subcontinent. This makes it easier to understand the rainfall pattern. Where the map shows yellow or green, the chances for rain are less, or even completely absent. Only where it is blue is there a reasonable chance for precipitation. Note also, that even Angola, Zambia and northern Mozambique are subject to limited high pressure control – not conducive for rain in Namibia as it blocks the route the moisture has to travel to reach us.

By Friday, the contiguous high has already split into two, setting up conditions for a mid-level trough next week that is expected to run from Angola through Botswana into South Africa.

On the Radar

Conditions over the weekend remain fairly static for the Namibian interior. The only exception is the Kavango, Bwabwata and Caprivi where a well-demarcated convergence zone is expected to develop.

There is a slight intrusion into the eastern parts close to the Botswana border, spreading deeper into the interior on Sunday but again with only limited rain prospects, and only from Windhoek further north.

On Monday sufficient moisture is still extant over the northern half but it will be a repeat of this week. Much promise with little rain although some heavy, very isolated falls may be experienced. No rain is expected for the southern half.

By Tuesday, the mid-level trough has developed to such an extent that there should be a broad intrusion of moisture from Angola running across Namibia from north to south. This leads to improved conditions for rainfall in the southern half by Wednesday. This activity will be limited to the interior above the escarpment.

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.
