October marks an important change in the malaria picture across Southern Africa. Temperatures are rising, the first rains are beginning in parts of the region and mosquito activity generally increases as the rainy season gets underway.
For travellers, October is therefore a good time to take malaria prevention seriously. The risk remains highly variable, however. A safari in Kruger National Park, a trip to the Okavango Delta, Victoria Falls, Zambia or Malawi carries a very different malaria risk from a visit to Cape Town, Windhoek or Lesotho.
Malaria recommendations also depend on your exact itinerary, accommodation, season of travel and individual health circumstances. If you are travelling to a malaria-risk area in October 2026, check current travel-health advice before departure and discuss whether antimalarial medication is appropriate for you.
Malaria risk areas in Southern Africa
Malaria transmission is not uniform across Southern Africa. Altitude, temperature, rainfall, proximity to rivers and wetlands, mosquito populations and the time of year all influence the risk.
The following is a practical October 2026 overview for travellers. It should not replace destination-specific medical advice, particularly for longer trips or travel to remote areas.
South Africa
Malaria risk in South Africa is concentrated in the north-east of the country and is seasonal.
Important risk areas include:
- Kruger National Park
- low-altitude parts of Mpumalanga
- low-altitude areas of Limpopo, particularly near the borders with Mozambique and Zimbabwe
- parts of northern KwaZulu-Natal
- border areas adjoining Mozambique and Zimbabwe
The main malaria transmission season in these areas runs from September to May, making October an important month for travellers visiting Kruger National Park and the Lowveld. Current travel-health guidance recommends antimalarial medication for some higher-risk areas during this transmission season, while other areas require bite avoidance without routine chemoprophylaxis.
There is no malaria risk in most of South Africa, including Cape Town, Johannesburg, Pretoria, the Garden Route and most of the Western and Eastern Cape.
Mozambique
Mozambique remains one of the region's most significant malaria-risk destinations. Malaria transmission occurs throughout the country, including popular coastal and safari destinations.
Travellers should take particular care when visiting:
- Maputo and southern Mozambique
- Inhambane and Vilanculos
- the Bazaruto area
- Beira and central Mozambique
- Gorongosa National Park
- Nampula
- Pemba and Cabo Delgado
- Niassa and other northern wilderness areas
Current travel-health guidance classifies Mozambique as a high-risk malaria country and recommends antimalarial medication for travellers, alongside mosquito-bite prevention.
October is especially relevant because the transition towards the rainy season can increase mosquito breeding opportunities.
Zimbabwe
Malaria risk varies with altitude and location in Zimbabwe. The Zambezi Valley and other low-lying areas remain important risk areas for travellers.
Popular destinations where malaria precautions are particularly relevant include:
- Victoria Falls
- Hwange National Park
- Zambezi National Park
- Lake Kariba
- Mana Pools
- Matusadona National Park
- Gonarezhou and the south-eastern Lowveld
- other low-lying areas along the Zambezi Valley
Current travel-health guidance considers the Zambezi Valley a year-round risk area. In much of Zimbabwe below 1,200 metres, the higher-risk transmission season begins in November, while July to October is generally considered a lower-risk period. October is therefore a transition month rather than a malaria-free month.
Travellers heading to Victoria Falls or the country's major safari areas should continue to use mosquito-bite precautions.
Zambia
Zambia remains a significant malaria-risk destination, including during October.
Malaria prevention is particularly relevant for travellers visiting:
- Livingstone and Victoria Falls
- South Luangwa National Park
- Lower Zambezi National Park
- Kafue National Park
- the Luangwa Valley
- the Zambezi Valley
- northern and eastern Zambia
Current travel-health guidance classifies Zambia as a high-risk malaria country and recommends antimalarial medication for travellers, together with bite avoidance.
For safari travellers, the combination of evening and nighttime exposure and accommodation in relatively open environments makes mosquito protection particularly important.
Botswana
October is a particularly important month for malaria awareness in Botswana.
The main risk is in the northern half of the country, including:
- Okavango Delta
- Moremi
- Chobe National Park
- Kasane
- Chobe and Linyanti
- the Kwando region
- Ngamiland
Current travel-health guidance identifies a high malaria risk in northern Botswana from October to May. During the remainder of the year, the same region is considered lower risk.
This makes October a significant seasonal transition for travellers planning an Okavango Delta or Chobe safari. The risk should not be judged simply by how dry the landscape looks: mosquito activity can increase as temperatures rise and seasonal rainfall develops.
Southern Botswana has considerably less malaria risk.
Namibia
Malaria risk in Namibia is concentrated mainly in the north and north-east.
Important areas include:
- Kavango East
- Kavango West
- Zambezi Region
- northern Kunene
- Omusati
- Oshana
- Ohangwena
- Oshikoto
- parts of Omaheke and Otjozondjupa
Current travel-health guidance identifies a high malaria risk throughout the year in Kavango East, Kavango West and the Zambezi Region. In several other northern regions, the risk is lower from May to November and increases during the wetter months.
For travellers, this means that October is a useful point to reassess malaria precautions, particularly if an itinerary combines Etosha National Park with the northern regions, Kavango or the Zambezi Region.
Windhoek, Swakopmund, Walvis Bay and most of southern Namibia have little or no malaria risk.
eSwatini
Malaria risk in eSwatini is considerably more localised than in neighbouring Mozambique.
The main areas of concern are the eastern Lowveld, particularly areas towards the Mozambique border. Higher-altitude areas, including Mbabane and much of the Highveld, have little or no malaria risk.
October is still generally a lower-risk period than the peak summer months, but travellers staying in the Lowveld should use mosquito-bite precautions. The seasonal pattern can change with temperature and rainfall, so an itinerary-specific assessment is preferable to treating the whole country as either “safe” or “unsafe”.
Malawi
Malaria is a major travel-health consideration throughout Malawi.
This includes popular destinations such as:
- Lake Malawi
- Liwonde National Park
- Majete Wildlife Reserve
- Nkhotakota Wildlife Reserve
- the Lower Shire Valley
- Lilongwe
- Blantyre
Current travel-health guidance considers Malaw a high-risk malaria destination and recommends antimalarial medication for travellers, in addition to mosquito-bite prevention.
The fact that October falls at the beginning of the rainy season in many parts of Malaw should not be interpreted as a sudden start to malaria risk: transmission occurs throughout the country.
Lesotho
Lesotho is different from most of its neighbours.
Malaria transmission does not normally occur in Lesotho, largely because of the country's high elevation and cooler climate. Travellers visiting Lesotho alone therefore do not normally require malaria prophylaxis specifically for their stay there.
The situation can change if a trip combines Lesotho with malaria-risk destinations elsewhere in Southern Africa. Your overall itinerary should therefore be considered when discussing malaria medication with a travel-health professional.
Angola
Malaria remains an important health risk throughout Angola, including in urban and lowland areas.
Travellers should not assume that staying in Luanda eliminates the risk. Much of the country has conditions suitable for malaria transmission, particularly warmer lowland and tropical areas.
For travellers combining Angola with other Southern African destinations, malaria prevention should therefore be considered as part of the overall itinerary rather than assessed only by individual stops.
Why October matters for malaria awareness
October is an important month for malaria awareness because Southern Africa is moving more decisively into the warmer part of the year.
Across many parts of the region, temperatures are rising and seasonal rainfall is beginning or becoming more frequent. Rainfall creates additional standing water and, together with warmer temperatures, can provide more favourable conditions for mosquitoes.
This is particularly relevant in northern Botswana, where October marks the start of the higher-risk malaria season according to current travel-health guidance. In South Africa, October falls firmly within the September-to-May malaria transmission season in the north-east.
October is also a popular month for Southern African travel. Safari destinations such as Kruger National Park, Chobe, the Okavango Delta, Hwange, Victoria Falls and South Luangwa remain attractive, while Mozambique's coast is another popular destination.
One common misconception is that malaria risk disappears when a destination looks dry. It does not. Malaria transmission depends on several factors, and risk can remain present even during relatively dry conditions.
Another important point is that malaria symptoms can initially look like many other illnesses. Fever, chills, headache, muscle aches, nausea and fatigue are common symptoms. Plasmodium falciparum, the malaria parasite responsible for most malaria in Africa, can cause severe disease rapidly if treatment is delayed.
If you develop a fever during a trip to a malaria-risk area or after returning home, tell the healthcare professional that you have travelled to a malaria area. Do not assume that malaria has been ruled out because you took preventive medication.
Malaria prevention tips for travellers
There is no single measure that provides complete protection against malaria. The best approach combines mosquito-bite avoidance with antimalarial medication when it is recommended for your destination and personal circumstances.
Before travelling
- Check your exact itinerary. Malaria risk can change substantially between neighbouring regions.
- See a travel-health professional before departure. Ideally, arrange an appointment around four to six weeks before travelling, although it is still worthwhile to seek advice at shorter notice.
- Discuss antimalarial medication. Whether you need prophylaxis depends on your destination, season, accommodation, activities and personal health circumstances.
- Take prescribed medication exactly as directed. Different medicines have different schedules before and after travel.
- Pack an effective mosquito repellent and make sure you know how to use it correctly.
While travelling
- Use an insect repellent containing an effective active ingredient such as DEET or picaridin (icaridin).
- Apply repellent to exposed skin according to the product instructions.
- Wear long trousers and long-sleeved clothing, particularly from dusk through to dawn.
- Choose accommodation with air conditioning, screened windows or other effective mosquito protection where possible.
- Sleep under an insecticide-treated mosquito net where one is provided.
- Keep doors and windows screened or closed when mosquitoes are active.
- Consider treating clothing or mosquito nets with permethrin where appropriate; permethrin should not be applied directly to skin.
Malaria-carrying Anopheles mosquitoes are predominantly active between dusk and dawn, so evening protection is particularly important on safari, at lodges and in other open-air accommodation.
After your trip
Don't forget about malaria once you have returned home.
A fever after travelling to a malaria-risk area requires prompt medical attention. Symptoms can develop after returning from Africa, and malaria can still occur despite having taken prophylactic medication.
Tell the doctor or emergency department that you have recently travelled to a malaria area and where you travelled. This information is important for diagnosis.
Malaria can progress quickly, particularly when caused by plasmodium falciparum. Anyone with suspected malaria should therefore be assessed urgently rather than waiting to see whether the fever improves on its own.
Final thoughts
October is an important point in the Southern African malaria calendar. The region is becoming warmer, seasonal rainfall is returning in many areas and mosquito activity can increase.
The risk nevertheless varies enormously. Northern Botswana enters its higher-risk season, north-eastern South Africa is in its main transmission season, while Mozambique, Zambia and Malawi remain significant malaria-risk destinations. Zimbabwe is entering a seasonal transition, Namibia has substantial regional differences, and Lesotho remains malaria-free.
For travellers, the most useful rule is simple: don't judge malaria risk by the month or country alone. Check your exact itinerary.
If you are travelling to a malaria-risk area in October 2026, obtain current travel-health advice before departure, use consistent mosquito-bite protection and take antimalarial medication when it has been recommended for you.
