Montana Conditions That Matter for Weddings

Most Days at or Above 90°F
Among listed Montana places with 10,000 or more residents, ranked by NOAA 1991–2020 normals. Here a restroom trailer's air conditioning, and the power it needs, matter most for summer receptions. Places that share a NOAA station show the same figure; ties are listed alphabetically.
- Billings: about 32 days a year at 90°F or more (NOAA 1991–2020 normals, Billings Logan Intl. Airport, MT station)

Trailer, Deluxe Units and Guest Count
The PSAI chart's smallest row, 500 guests, calls for 2 units for one hour and 6 for five hours; most weddings are smaller, so treat it as an upper bound and add 10–20% for a bar. A restroom trailer needs a level spot, a power source and a lit path; deluxe units need no hookups.
In the 27 listed places with 120+ freezing nights, cold-season weddings need a heated trailer with protected water lines.
Who Handles Local Rules
For a wedding in a public park or on other public land, or a restroom trailer parked on a street, the government to ask depends on where the site is. Of the 27 listed Montana places, 19 are incorporated, 8 are unincorporated Census-designated places. In an incorporated place, ask the city, town, village or borough; in an unincorporated community, ask the county. We don't say whether a permit is needed; each city page names who to ask.
What to Ask For
- Guest count and reception hours
- Restroom trailer or deluxe flushable units
- Power (outlet or generator) and level ground for a trailer
- A lit path from the reception area
- An accessible unit if any guest uses a wheelchair or walker
