What Happened

The cooling effect of the South Atlantic high pressure cell was felt at the beginning of the week, followed by a gradual return to warmer temperatures, both night and day, as the high shifted to the eastern half of the sub-continent.

The colder Sunday and Monday nights manifested as far north as Otjiwarongo with the biggest impact in the Karas Region, and then a day later (Tuesday) in the Kalahari. By Wednesday conditions returned to an early-winter “normal” but nighttime temperatures generally remained above 10°C. The days were much warmer, hot even, around Mariental, the central northern areas, and the Kunene region.

At the beginning of the week, airflow over the interior was predominantly south with windy conditions above the escarpment. This lasted only a day and by Wednesday, the interior has settled while the wind direction veered to north-east. This change in wind direction brought in a layer of cloud from the north-east which originated in a weak low pressure system over Western Zambia. Scattered clouds continued to penetrate the interior from the Kavango during Wednesday and Thursday but the intrusion presented itself as a classic inversion layer, i.e. a high cloud base between 12,000 and 14,000 feet, and flat cloud tops thus little room for convection.

Except for isolated pockets in the Kavango and Bwabwata, none of the available satellite images portrayed anything remotely resembling a rain-bearing system.

The visual chosen for the week shows a precipitation outlook for the first week of June. Although these outlooks hardly every pan out the way they are projected 12 days earlier, there are however some very pointing clues regarding the general expectation for the winter.

As can be seen from the image, the outlook is based on a very normal Western Cape winter. This indicates that atmospheric conditions on a regional scale have normalised or are expected to continue moving closer to the 30-year mean. On a wider arena, this is corroborated by the Southern Oscillation Index of the Australian Bureau of Meteorology which have turned negative over the past three weeks, but is still regarded as “neutral.” This is a sign of a decaying La Nina in the western equatorial Pacific. Similarly, several ENSO trackers now show sea surface temperatures in the central and eastern Pacific to be reverting to mean, another sign that the La Nina is terminal.

It is still too early to tell how quickly the La Nina, once gone, will transition to warmer El Nino conditions but the general consensus among scientists is that conditions will remain neutral, at least until the end of the northern hemisphere summer, or even up to the end of the year.

If the short-term regional outlook for southern Africa assumes a normal winter stance, and if the leading American, Australian and European met institutions expect a return to neutral, the only safe view now, is that Namibia can expect a relatively normal winter and a normal early rain season later in the year.

If this indeed turns out to be the case, there will be several opportunities for the southern Namib and the Orange River Valley to receive some light rain during the next two months as a spill-over from the Western and southern Cape systems. This precipitation, however, is measured in ones and twos. It may also produce some snow in the Aus region, something which has not occurred for several years.

What’s Coming

Not much activity is expected over the long weekend. The current high pressure cell over the sub-continent stays in place during Friday and Saturday, ridging in over the Hardap and Karas Regions but it is not accompanied by a frontal system.

There is some low pressure intrusion along the coastal plain but the pressure differential is so slight, that if Oosweer is present, it will be mild. The northern Namib may experience windy conditions on Sunday.

It is only by next week Monday night that a change in conditions is expected. The South Atlantic high is then only some 200 km offshore Lüderitz and its impact will be felt on Tuesday and Wednesday. As the South Atlantic high moves onto the main land, its ridges again into Namibian airspace penetrating the territory from the south-east. The core however, remains offshore so while next week will present some cooler nights across most of the interior south of Etosha, the threat of frost is minimal.

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.
