Porta Potty Rental in Sandy Oaks, TX

Planning Around the Weather

DOE's Building America map puts Bexar County in the Hot-Humid climate region (IECC 2021 zone 2A, PNNL county guide). This region pairs heat with humidity for much of the year; for long rentals in the hot months, ask how often units will be serviced.

Heat

About 134 days a year reach 90°F or more, more than nine in ten U.S. places in our data, so heat is the normal condition for months at a time. About 34 of those days reach 100°F, which is top-tenth territory nationally. For long rentals in the hot, humid months, ask how often units will be serviced. For rentals longer than a day in the warm months, set servicing by the heat rather than the calendar, shade the units, and add hand-wash stations.

Occasional Freezes

Only about 14 nights a year reach 32°F (fewer than three in four U.S. places in our data), but one hard freeze is enough to damage anything that holds water. For winter dates, ask what the provider does with water-carrying units when a freeze is forecast.

Events, Weddings and Parties

On one of Sandy Oaks's hot days, a five-hour event for 1,000 people needs 9 units on the PSAI event chart, or 10 to 11 with alcohol (PSAI adds 10–20%). Every cluster of restrooms needs at least 5% accessible units, rounded up, so even a two-unit cluster includes an ADA unit.

With only about 14 freezing nights a year, summer is the season to plan around; for a summer wedding, a restroom trailer brings air conditioning but needs a power source, while deluxe units need no hookups. On 100°F days, put drinking water and shade near the restroom rows, not just the stage. More: event rentals in Texas and wedding restrooms in Texas.
