In 2025 the busiest month for international visitor arrivals was Canada (July), the USA (August), Australia (December), New Zealand (December), Singapore (July), Mexico (December), Brazil (January), Hong Kong (August) and Argentina (January). Each place counts arrivals differently, so compare the months, not the percentages.

Busiest and quietest months, 2025
| Country | What is counted | Busiest | Quietest |
|---|---|---|---|
| Canada | Overnight visitor arrivals | July | January |
| USA | Overseas visitor arrivals | August | February |
| Australia | Short-term visitor arrivals | December | May |
| New Zealand | Overseas visitor arrivals | December | June |
| Singapore | International visitor arrivals | July | June |
| Mexico | International tourist arrivals | December | September |
| Brazil | International tourist arrivals | January | June |
| Hong Kong | Visitor arrivals, including same-day visitors | August | September |
| Argentina | International tourist arrivals | January | May |
The busiest months: Brazil and Argentina in January; Canada and Singapore in July; the USA and Hong Kong in August; Australia, New Zealand and Mexico in December.1 The data shows when; it does not show why, and we have not guessed.
Why don't we rank these countries?
Because they measure different things. Canada's figure counts overnight visitors crossing its border. The USA's counts overseas visitors staying at least one night, and leaves out Canada and Mexico. Australia and New Zealand count visitors planning to stay less than a year. Singapore counts visitors staying less than a year but leaves out Malaysians arriving by land. Mexico counts tourists who stay at least one night, including those who stay only in the border zone. Argentina counts tourists who stay at least one night and publishes them in thousands. Brazil counts non-resident tourists staying at least one night, from migration records at its borders. Hong Kong counts visitor arrivals, including same-day visitors and visitors from the Chinese Mainland, Macao and Taiwan. Putting their percentages side by side would suggest a comparison the data cannot support.
Each country page explains exactly what is counted and links to the source.
What about the UK and South Korea?
For these two we found no complete 2025 monthly count of visitors that we may reuse, so we show border counts instead: every foreign national arriving, whatever the reason for the trip. They are not visitor counts, and they are not in the table above.
| Country | What is counted | Busiest | Quietest |
|---|---|---|---|
| UK | Non-British arrivals at the UK border | July | February |
| South Korea | Foreign nationals entering South Korea | August | January |
What about Europe and Japan?
Those pages use hotel nights rather than arrivals, which is a closer measure of how busy places to stay are. See Off-season in Europe and Off-season in Japan.
