Extra! Extra! Read All About It! Total Lunar Eclipse 7 September 2025

This is a celestial event you won’t want to miss — and one of the best lunar eclipses visible from South Africa in years.

Stargazers around the country have been waiting impatiently for a stunning astronomical spectacle that’s taking place on the night of Sunday the 7th of September 2025, when a rare total lunar eclipse, commonly called a Blood Moon, will be visible across the country. Grab your warm jackets (it can still be cold during September evenings) and get comfortable as the sky puts on an amazing show!

Vox Weather Meteorologist Michelle du Plessis tells us more about how lunar eclipses are formed, and the weather we can hope for on Sunday night.

What is a Lunar Eclipse?

A lunar eclipse happens when the Earth passes directly between the Sun and the Moon, casting its shadow onto the Moon. This only occurs during a full moon.

There are three types of lunar eclipses:

  1. Penumbral Lunar Eclipse – the Moon passes through Earth’s faint outer shadow (the penumbra), causing only a slight dimming.
  2. Partial Lunar Eclipse – part of the Moon passes through Earth’s dark central shadow (the umbra), and a section appears darkened.
  3. Total Lunar Eclipse – the entire Moon moves into Earth’s umbra, turning a reddish colour — often called a ‘Blood Moon’.

 

During a total lunar eclipse, the Earth blocks direct sunlight from reaching the Moon. However, sunlight still filters through Earth’s atmosphere and bends (or refracts) around the planet.

Shorter blue wavelengths are scattered, and the longer red and orange wavelengths reach the Moon — causing it to glow red or copper.

It’s the same effect that gives us red sunrises and sunsets — except this time, you’re seeing it reflected back from the Moon!

This TikTok video from Michelle shows us more on how lunar eclipses take place – together with a quick weather overview for the country’s stargazing.

The 7 September 2025 eclipse is special because:

  • It will be a total lunar eclipse, with the entire Moon turning red.
  • It will last 82 minutes, making it one of the longest lunar eclipses of the decade.
  • It will be visible across South Africa.
  • No telescope is needed — you can see it with the naked eye if skies are clear.

South Africa Viewing Details and Weather Conditions

The table shows the key moments to look out for. The best time to watch is between 7:30 PM and 8:52 PM, when the Moon will be completely within Earth’s shadow and glowing red.

The weather conditions for 7 September across the country will be mostly favourable for viewing the total lunar eclipse on Sunday evening.

  • However, around the Southern Cape, including parts of the Garden Route and Overberg, we are expecting widespread cloud cover, which will most likely obscure the view of the eclipse.
  • In contrast, much of the interior, including the Free State, North West, Limpopo, and Gauteng, will experience partly cloudy skies with high to mid-level cloud, allowing for intermittent but generally good visibility of the eclipse.
  • Cape Town is also expected to have clear enough skies, especially earlier in the evening, making for a great viewing opportunity.
  • Coastal areas in KwaZulu-Natal and parts of the Eastern Cape may see some coastal cloud or mist, especially early evening, but breaks in the cloud are possible later on.

For the best view, try to find an open area away from city lights — ideally elevated, with an unobstructed view of the eastern horizon where the Moon will rise.

Tips for Watching and Photographing

  • Dress warmly — it’s still chilly at night in September.
  • Use a camera with manual exposure settings if possible.
  • For smartphone users: Tap to focus on the Moon and reduce brightness for better contrast.

 

Fun Facts

  • A lunar eclipse can only occur during a full moon.
  • Unlike a solar eclipse, lunar eclipses are safe to view with the naked eye.
  • The Moon doesn’t completely disappear — it turns red due to Rayleigh scattering in Earth’s atmosphere.

Why Is It Called a “Blood Moon”?

The term ‘Blood Moon’ comes from the deep red colour the Moon takes on during totality. Ancient cultures often saw it as an omen, but today we know it’s simply the effect of Earth’s atmosphere bending sunlight.

Mark your calendars and if skies are clear, look up and enjoy the show!

How SA’s winter weather patterns compare to our neighbours

South Africa is one of the few countries in southern Africa that regularly has snow  – in places – in winter.

Vox Weather Meteorologist Michelle du Plessis tells us more.

South Africa’s climatic diversity is largely due to its geographic position at the southernmost tip of Africa, where it’s influenced by both the warm Agulhas Current on the east coast and the cold Benguela Current on the west coast. Its varied topography – ranging from high plateaus to mountain ranges like the Drakensberg – creates conditions cold enough for snowfall in winter. Being the furthest south on the continent, South Africa is also directly affected by mid-latitude cyclones and cut-off low-pressure systems. When looking at our neighbouring countries, clear contrasts emerge in winter weather patterns.

Lesotho, though an independent country, is entirely landlocked within South Africa.

Its high elevation – most of the country lies above 1,800 metres – means it experiences regular snowfall in winter, particularly over the Maloti Mountains, much like surrounding high-lying areas of South Africa.

Namibia and Botswana experience dry, sunny winters with cool nights and warm days, but their generally low elevation and arid conditions make snowfall virtually impossible.

In Namibia, bergwinds or “oosweer” often bring warm, dry weather and occasional sandstorms as strong north-easterly winds prevail after the passage of cold fronts. Although rare, light snowfall can occur in the far south of Namibia when a particularly strong cold front moves unusually far north.

Zimbabwe and Mozambique have subtropical to tropical climates. Their winters are dry and mild, with average temperatures rarely dropping low enough to produce frost, let alone snow.

Eswatini experiences slightly cooler conditions in winter, especially in its highland areas, but snowfall is extremely rare due to its lower elevation and more humid climate.

These regional differences highlight how South Africa’s southern location, combined with its topographical range and oceanic influences, makes it uniquely positioned to experience a wide variety of winter weather, including rain and snow – conditions seldom seen in its neighbouring countries.

Snow a possibility for Gauteng as cold weather grips SA

GARDEN ROUTE | KAROO NEWS – While snowfall is likely to evade Gauteng, a strong cut-off low will develop over the western part of the country on Wednesday and slowly move eastwards, spreading cold and wet weather over central and later eastern parts of South Africa. 

According to Vox Weather, models are indicating a mix of rain, snow, and graupel is likely over central South Africa (parts of Free State, Northern Cape, Eastern Cape, Lesotho).

The Effect of Climate Change on South Africa’s Winter Weather Patterns

What is happening to SA’s winters and is climate change playing a significant role? Vox Meteorologist Michelle du Plessis tells us more.

Data shows that winter temperatures across southern Africa have been steadily rising since the 1960s, with fewer days of frost and freezing conditions.

According to the NOAA, extreme cold events are now far less common – and when they do happen, they’re generally milder than in the past.

In the Western Cape, where winter rainfall is vital, climate models show that the rainy season is becoming shorter and more variable.

While some winters still bring strong cold fronts and good rainfall, others are marked by long dry spells.

The WMO warns that drought risks are increasing, especially in Mediterranean-type climates like the south-western Cape.

Interestingly, while total rainfall may decrease, when storms do occur, they may be more intense – bringing short bursts of heavy rain rather than steady soaking periods. This is because warmer air holds more moisture, which can lead to more powerful frontal systems when they develop.

Recent studies suggest that mid-latitude frontal systems – the cold fronts that bring winter rain – may grow stronger under climate change. However, this doesn’t mean we’ll get more of them. Instead, we may see fewer, but more intense, winter storms, followed by longer dry periods in between.

What this means for South Africa

In short, South African winters are becoming:

  • Warmer, with fewer frost days;
  • More variable, with rain falling in short, intense bursts; and
  • Less predictable, meaning long-range planning is harder.

A Note on Snow Forecasting at Vox Weather

Some early snow forecasts recently circulated on social media suggested possible snowfall over parts of Gauteng, North West, the Highveld, and other areas that rarely experience snow during late July. At Vox Weather, we chose not to post about these projections – and here’s why.

Advanced snow forecasts, particularly more than five days ahead, are often subject to significant change. In fact, updated model guidance today NO LONGER indicates snowfall over these north-eastern regions at all.

Our approach as meteorologists to snow forecasting involves more than just looking at model snowfall outputs.

We analyse:

  • The SYNOPTIC SYSTEM expected (e.g. a cold front or cut-off low);
  • The availability and timing of PRECIPITATION; and
  • The FREEZING LEVELS (the altitude at which temperatures are cold enough for snow to form and reach the ground).

These factors must all align for snowfall to be possible. A shift in any of them can lead to significant changes in where snow may fall – or if it occurs at all.

As of the latest forecast, we see:

  • A cold front expected to move in on Friday 25 July.
  • A strong ridging high-pressure system to follow, introducing colder air over southern South Africa during the weekend of 26 and 27 July.
  • Forecast snowfall now largely restricted to the Eastern Cape, Lesotho, the southern Free State, and adjacent high-lying areas.

At Vox Weather, we prefer to wait until we see consistency in multiple forecast runs – usually within a five-day window – before communicating potential snowfall.

 

This ensures that our updates are as accurate and reliable as possible.

Snow Patrol!

The arrival of snow isn’t an everyday occurrence for most of South Africa.

As we find ourselves back in snow season, we sat down with Vox Meteorologist Michelle du Plessis to give us the lowdown on how snow is formed.

And it turns out that, for snow to fall and reach the ground, three main weather conditions must come together.

Cold air from top to bottom: The air must be below freezing (0 °C) all the way from the clouds to the ground. If there’s a warmer layer in between, the snow will melt and fall as rain or sleet. Ideal snow forms in clouds where temperatures are between -10 °C and -20 °C.

Enough moisture in the air: Cold air alone isn’t enough – you also need moisture so that water vapour can form ice crystals. Dry air, even if freezing, won’t produce snow.

Something to lift the air: Snow usually forms when air is forced to rise, cool, and condense. This can happen with cold fronts, low-pressure systems like cut-off lows, or when air is pushed up over mountains.

Gauteng’s last snowfall: July 2023…

In July 2023, Gauteng experienced rare snowfall – something locals hadn’t seen in over a decade (before 2023 it snowed in 2012 and 1996). While light snow sometimes falls in the province, heavier events like this happen only once every 10 to 20 years. So yes, it was unusual, but not unheard of.

The July 2023 cold snap wasn’t driven by climate change – instead, it was the result of a powerful cold front that swept across the entire country and extended into our neighbouring countries – supported by a steep upper-air trough, pushing icy air far north.

Looking ahead to winter 2025…

We find that the odds of another snowfall in Gauteng remain low. Climate trends suggest snow in the region will become even rarer in future. That said, nature still has surprises.

If the right weather patterns align—such as a strong cold front or cut-off low pressure system – we could see isolated snow again. But it would remain the exception, not the rule.
