2. Lima, Peru
Average daily cost (excluding flights): $60–$80
Lima is ideal for those seeking a blend of culture, history, and cuisine, all on a budget. September falls during Peru's shoulder season, meaning fewer crowds and better prices. The exchange rate from USD to Peruvian Sol makes it even more affordable.

3. Bangkok, Thailand
Average daily cost (excluding flights): $30–$60
Thailand is one of the most affordable countries to visit year-round, and Bangkok remains a favorite for cheap September vacations. In September, the rainy season means fewer tourists, which also leads to better deals on flights and hotels.
