Missouri Conditions That Matter for Events
Across the 141 Missouri places listed here (NOAA 1991–2020 normals by nearest station):
- 2 of 141 listed places average 60+ days a year at 90°F
- 34 of 141 listed places are in the wet band (46+ inches a year or 12+ days with an inch)
- All 141 listed places average 30+ nights a year at 32°F
Conditions differ enough across the state that the city pages are the better guide; the PSAI sizing below applies everywhere.
Range Across the State
Across the 141 listed Missouri places with this figure (NOAA 1991–2020 normals), the low end is about 24 days a year at 90°F or more (Hannibal) and the high end about 64 (Kennett and Caruthersville); the middle place is near 44.
By Climate Region
By DOE Building America climate region (county level, PNNL guide), the planning focus shifts: Mixed-Humid (134 places): heat planning in summer and water-free units in winter; Cold (7 places): an outdoor season limited by long freezing winters.
Most Days at or Above 90°F
Among listed Missouri places with 10,000 or more residents, ranked by NOAA 1991–2020 normals. These are the places where event servicing, shade and hand-wash water need the most planning. Places that share a NOAA station show the same figure; ties are listed alphabetically.

How Many Units
The PSAI chart sizes event restrooms by crowd and hours, assuming no servicing during the event:
| Crowd | 1 hr | 2 hrs | 3 hrs | 4 hrs | 5 hrs | 6 hrs | 7 hrs | 8 hrs |
|---|---|---|---|---|---|---|---|---|
| 500 | 2 | 4 | 4 | 5 | 6 | 7 | 9 | 9 |
| 1,000 | 4 | 6 | 8 | 8 | 9 | 9 | 11 | 12 |
| 2,000 | 5 | 6 | 9 | 12 | 14 | 16 | 18 | 20 |
| 5,000 | 12 | 15 | 20 | 25 | 31 | 38 | 44 | 50 |
| 10,000 | 15 | 25 | 38 | 50 | 63 | 75 | 88 | 100 |
For a five-hour event of 1,000 people, the chart gives 9 units; with alcohol, 10 to 11, and at least 1 accessible unit per cluster.
Who Handles Local Rules
For a special event on public property, a park reservation, or restroom rows on a street or sidewalk, the government to ask depends on where the site is. Of the 141 listed Missouri places, 128 are incorporated, 13 are unincorporated Census-designated places. In an incorporated place, ask the city, town, village or borough; in an unincorporated community, ask the town or township, or the county. We don't say whether a permit is needed; each city page names who to ask.
What to Ask For
- Expected attendance, including staff, vendors and volunteers
- Event hours and whether it runs over several days
- Whether alcohol or food will be served
- ADA units (at least 5% of each cluster) and hand-wash stations
- Delivery and pickup windows the venue allows
