When to go
Most trips are decided the other way round from how they should be: people choose a place, then discover the month works against it. This page inverts that. Pick the month you can actually travel, and see which of our 20 destinations is at its best then, which is in a weaker period, and why.
Each destination shows two separate things: our own stated stronger and weaker periods, and the sourced historical record for that month (2015–2024). Historical records describe what a month has typically been like. They are not a forecast.
In September, 12 of 20 destinations are in one of their stronger periods.

Understanding the seasonal trade-off
Choosing a month is rarely about temperature alone. These two questions decide most trips.

Shoulder season is usually the better choice for walking, cities and cost, and usually the worse choice for swimming — because sea temperature lags air temperature by roughly a season.
