Ethiopia can be visited at any time of year, but different seasons have different advantages.
Conventional wisdom is that visitors should avoid the rainy season, which usually starts in June, but peaks over July and August in the central and northern highlands. Certainly, highland towns such as Gondar, Lalibela and Addis Ababa can be very damp and cool during the rains. That aside, however, recent improvements in the northern circuit’s road network makes the rains far less of an obstacle to travel than would have been the case few years ago. The countryside is also very green and scenic during the rains, and you’ll encounter fewer tourists at popular sites such as Lalibela.
The late rainy season, from September through to early October, is a lovely time of year. There’s a significant drop in precipitation over this period, but the countryside is very green, and punctuated by yellow meskel wild flowers. On 27 September (a day later in leap years), Ethiopia erupts into festival mode to celebrate Meskel, which commemorates the finding of the True Cross more than 1600 years ago.
Arguably the optimum time to visit Ethiopia is from mid October to January, when the rains are over but the countryside is still quite green. This is also the peak tourist season, so facilities and sites of interest tend to be busier than at other times. It is well worth aiming to be in Lalibela or Gondar for Timkat (Ethiopian Epiphany), another wonderfully colourful celebration held on 19 January (except on leap years).
The late dry season, from February to May, is also a good time to visit, though the scenery tends to become dryer and browner towards the end of this period, except in the far south where the first rains often fall as early as April.
Wildlife can be observed throughout the year, but the European winter – November to March – is particularly rewarding for birders, as resident species are supplemented by large numbers of Palaearctic migrants.
Ethiopia is a safe and reasonably healthy country provided you take a few common sense precautions.
Ensure your inoculations for typhoid, tetanus, polio and hepatitis A are up to date, mainly if you are traveling out of the capital or you will stay away from the largest hotels
Anti-malarial prophylactics should be taken if you’ll be visiting low-lying moist regions such as the southern Rift Valley and South Omo. There is also a small risk of malaria, especially during the rainy season, at mid-altitude sites such as Bahir Dar and Harar. Malaria is all but absent above 2000m, for instance in Addis Ababa, Gondar, Lalibela and the Bale and Simien mountains.
Avoid drinking or brushing your teeth with tap water. Bottled water is safe and widely available.
Its a good idea to carry a few packs of antiseptic wet wipes to wash your hands after toilet stops or before meals in more remote areas where running water may not be available.
Ethiopia is a safe and politically stable country, though there may be some risk attached to travel in remote border areas with more volatile neighbours such as Eritrea, Somalia, Sudan and South Sudan. None of these areas is likely to be visited on a normal tour.
Pickpockets and con artists proliferate in central Addis Ababa but are not a serious cause for concern elsewhere in the country.
All visitors to Ethiopia require visas. The only exceptions are nationals from Djibouti and Kenya and travelers who arrive at Addis Ababa Bole International Airport to catch a connecting flight.
