What the curve means for planners
In Washington, D.C., the month on the booking is a budget decision. Rates swing 44% between the cheapest and priciest months, one of the wider gaps in the 50 markets we measured.
August is the floor at $179 a night, 29% below the $252 average, while May peaks at $317, 26% above it.
If the destination is fixed but the dates are not, this is the market where it pays to schedule around the curve. Moving a multi-night group stay out of May changes the total more than most rate negotiations will.
Why do hotel prices in Washington, D.C. move this way?
The pattern below is measured. The explanation is our read of it.
The curve lines up with the federal calendar so neatly that we treat that as the explanation. Rates peak from March through May while Congress is in session and advocacy season runs at full tilt, collapse in August during the congressional recess, then surge again in September and October as the fall session and conference season resume. December and January, we assume, belong to the holidays and the year-end lull.

When should I book a hotel in Washington, D.C.?

For Washington, D.C., that means aiming for August and avoiding May when dates are flexible. Our full study, Every City Has a Season, covers how timing plays out across all 50 markets.
This page is one market from a 50-city study of how hotel prices move through the year.
How we did this
The figures on this page come from the 128,536,941 hotel prices that business travelers saw when searching on Engine, a platform companies use to book work trips, across 50 U.S. markets over roughly two years (May 2024 to April 2026).
What we measured. Every data point is a par rate, meaning the cheapest publicly available nightly rate a hotel offered at the moment of a live search. These are the prices companies see while planning a trip, not Engine's negotiated rates and not the prices ultimately booked. Real corporate rates typically sit below what is shown here.
Whose trips we looked at. We focused on planned travel and included only searches made 10 to 180 days before check-in, limited to business accounts, with internal, test, and promotional activity excluded.
A few caveats. These are advertised rates, not final booked prices. Monthly figures pool multiple years to smooth year-to-year noise, so an unusually large one-off event can occasionally push a single city-month higher than a typical year.
