When to book a hotel, from measured prices

How much does the month matter?

As of Aug 2026, the widest cheapest-to-dearest-month gap among the 12 cities we track is Barcelona’s: a median of $148 a night in December against $362 at its peak — 59% off the peak price for the same rooms, just by moving the trip. At the other end, Bangkok moves only 20% across its whole year ($63 to $78), so there timing buys little — go whenever suits you.

Neither number is a rule of thumb; each is this year’s measured curve for one city. The ranked table on the homepage shows where every city we track falls between those two ends.

Cheap for the city, not cheap on the map

The useful comparison is a city against its own normal, not against other cities. A $70-a-night city beats a $200 one on absolute price in every month of the year, which tells you about the cities and nothing about timing. The question timing can answer is: how far below its own usual price is this city in the month you can travel? That is how every ranking on this site is computed.

As of Aug 2026, the best-placed city inside the next 3 months by that measure is Rome in November — a median of $185 a night, 29% below what Rome normally costs.

If you have a month and no destination, the month pages rank every city for it. If you have a destination and no dates, its city page opens with the cheapest and dearest months we measured.

What about booking further ahead?

We can’t tell you, and we’d rather say so than guess. Our probes hold the booking lead time constant on purpose — that is what makes month-to-month comparisons honest — so our data measures when to go, not how far ahead to buy. We also don’t predict prices: we can tell you what a room has cost and how much it swings, not what it will do next week.

What the nightly record does support: a specific room, on specific dates, priced below its own recorded normal — today. That is what a deal on this site is, and watching a city is how you hear about one without checking back.
