Travelling to Southern Africa in May offers excellent safari conditions, cooler temperatures, and fewer crowds. However, malaria remains an important health consideration in several regions. While the peak transmission season is coming to an end, the risk does not disappear entirely.
This guide explains where malaria risk remains in May, why awareness is still important, and how travellers can protect themselves effectively.
Malaria Risk Areas in Southern Africa
Malaria transmission in Southern Africa is mostly seasonal, typically occurring between September and May, with peak risk during the warmer and wetter months from January to April. However, countries such as Zambia and Malawi have year-round risk.
By May, the risk is generally declining, but it remains present—especially in low-lying and warmer regions.
Key Malaria Risk Areas
- South Africa
- Botswana
- Namibia
- Zambezi Region (Caprivi Strip)
- Kavango East and West
- Northern regions near Angola
- Zimbabwe
- Mozambique
- Most of the country, especially coastal and northern regions
- Zambia
- South Luangwa National Park
- Lower Zambezi National Park
- Kafue National Park
- Victoria Falls (Zambian side)
- Malawi
- Lake Malawi (all shores and islands)
- Liwonde National Park
- Majete Wildlife Reserve
- eSwatini
- Lowveld regions in the east
- Areas bordering Mozambique and South Africa
What changes in May?
- Malaria risk begins to decrease as temperatures drop
- Mosquito activity reduces but does not stop completely
- Residual transmission can continue after a strong rainy season
Even in May, “low risk” does not mean “no risk,” particularly in popular safari destinations.
Why May matters for malaria awareness
May is often seen as a safer travel month, but from a health perspective it remains a transitional period.
End of peak season does not mean zero risk
Although malaria cases decline after April, transmission can continue due to:
- Remaining standing water from the rainy season
- Warm daytime temperatures
- Ongoing mosquito activity
Increased Travel to Safari Regions
May marks the start of prime safari season, with:
- Improved wildlife visibility
- Drier landscapes
- Comfortable weather conditions
This also means more travellers are visiting malaria-risk areas such as Kruger National Park, the Okavango Delta, and Victoria Falls.
Delayed onset of symptoms
Malaria symptoms can appear 7 to 30 days after infection. Travellers may only become ill after returning home, making awareness and early diagnosis critical.
Malaria prevention tips for travellers
Malaria is preventable and treatable, but requires a proactive approach.
1. Consider antimalarial medication
If you are travelling to a malaria-risk area:
- Consult a travel health professional before departure
- Take prescribed prophylaxis as directed
- Start before travel and continue after your trip
2. Prevent mosquito bites
Mosquitoes that transmit malaria are most active from dusk to dawn.
Protect yourself by:
- Using insect repellent containing DEET (10–30%)
- Wearing long sleeves and trousers in the evening
- Sleeping under mosquito nets where necessary
- Using air conditioning or fans
- Keeping doors and windows closed or screened
3. Choose accommodation carefully
Select accommodation with:
- Screened windows or mosquito nets
- Air conditioning where possible
- Effective mosquito control measures
Many safari lodges are well-prepared, but it is always worth confirming.
4. Be aware of symptoms
Seek medical attention immediately if you experience:
- Fever
- Chills
- Headache
- Muscle aches
- Fatigue
Symptoms can develop even after you have returned home.
5. Travelling with children
Children are more vulnerable to malaria:
- Use age-appropriate prophylaxis
- Apply child-safe insect repellent
- Prioritise mosquito-protected accommodation
Final thoughts: Travel smart in May
May is an excellent time to visit Southern Africa, offering outstanding safari experiences and comfortable conditions. However, malaria risk remains in certain regions and should not be overlooked.
With the right precautions—bite prevention, appropriate medication, and awareness of symptoms—you can travel safely and confidently.
