If you are booking a flight to Lagos between roughly November and March, you may hear about the Harmattan. This seasonal dry wind brings dusty, hazy air across West Africa, and it can affect how the trip feels. It rarely stops travel, but a little preparation helps. Here is what to expect.

The Harmattan usually means drier air, cooler mornings and a layer of fine dust that can reduce visibility. The haze may look like fog, and it can make the sun appear dim. Strength and timing vary from year to year, so treat any description as a general guide rather than a promise.

Flights can occasionally be affected when visibility is poor, so keep some flexibility in your plans. Avoid tight connections and important appointments on the day you land. If your flight is delayed, speak to the airline promptly and keep your boarding pass and receipts. Check your flight status before leaving for the airport.

Look after your skin and eyes. The dry air can cause chapped lips, dry skin and irritated eyes. Pack lip balm, moisturiser and eye drops, and drink plenty of water during the flight and after arrival. If you wear contact lenses, bring glasses as a backup.

Think about your health. Dust can bother people with breathing difficulties, so speak to your doctor before travelling if this applies to you. Carry any regular medication in your hand luggage with a copy of the prescription. A light scarf or mask can help on particularly dusty days.

Pack for changing temperatures. Mornings and evenings can feel cooler, while afternoons stay warm. Light layers work best, along with comfortable shoes and sunglasses. Protect cameras and electronics from dust with pouches or cases, and keep spare chargers in your hand luggage.

Use the season to your advantage. Fares outside the Christmas peak can be more reasonable, and many people enjoy the drier weather for visits and events. Compare dates around your preferred travel window, and check what each fare includes, especially baggage and change rules.

The Harmattan is simply part of the calendar in West Africa, and most travellers manage it easily. Pack sensibly, stay flexible and look after your health. A travel agent can help you compare fares and dates, so you can plan your trip around the season with confidence.
