City tours in Dar es Salaam can be enjoyed year-round, but the dry season (June to October) offers more pleasant weather for exploring on foot. During this time, the heat and humidity are lower, making it comfortable to visit markets, museums, and coastal sites. The wet season (November to May) brings occasional rains, but mornings are often clear, and it's still possible to enjoy a half-day or full-day city tour combined with local dining and beachside relaxation.
