The best time to go to New England, Sierra Leone, is during the dry season, which typically runs from November to April.
During these months, you'll experience less rainfall and lower humidity, making it much more comfortable for exploring. The drier conditions are ideal for outdoor activities like hiking and wildlife viewing, and the roads are generally in better condition, which is a major convenience for travellers.
For those interested in exploring the local culture and historical sites, the dry season offers pleasant weather for walking around Freetown and visiting places like the Sierra Leone National Museum or the Cotton Tree. The clearer skies also make for better photography opportunities.
If your trip involves beach relaxation or water-based activities along the coast, the dry season's sunny days are perfect.
