Climate in Universal City
Universal City shares San Antonio's humid subtropical climate -- hot, muggy summers and mild winters -- with hail as its real, dominant severe-weather risk rather than the flood or hurricane exposure seen in other parts of Texas covered in this dataset.

San Antonio's humid subtropical climate brings average June highs around 92°F, rising to roughly 96.6°F in August, with humidity remaining high (dropping only to around 59% at its lowest) through the June-September stretch; winters are mild to cool (weather-and-climate.com / climate.top aggregation, retrieved 2026-08-22). Universal City, immediately northeast of San Antonio, shares this regional pattern.
Hail is the dominant, well-documented severe-weather risk
San Antonio averaged 4.4 severe hail days per year from 2016-2025 -- the highest 10-year average on record for the area -- and Bexar County saw weather-related insurance claims rise 15% from 2023 to 2025 (Canopy Insurance Texas, retrieved 2026-08-22). This is a materially different hazard profile than Kyle's Hill Country flash-flood exposure covered elsewhere in this dataset's Tier B batch, or than Gulf Coast hurricane exposure -- Universal City's risk is inland severe convective storms (hail, high wind), not tropical systems.
Flood exposure is real but limited, per the city's own floodplain map
The City of Universal City's own floodplain map shows most of the city in FEMA's Zone X (areas not recognized as high hazard, including both the unshaded minimal-risk zone and the shaded 0.2%-annual-chance/500-year-floodplain zone), with only limited areas mapped as Special Flood Hazard Area (Zones A/AE, the 1%-annual-chance/100-year floodplain) (City of Universal City, retrieved 2026-08-22). This is a meaningfully lower flood profile than the Hays County "Flash Flood Alley" exposure documented for Kyle elsewhere in this batch -- though buyers should still check a specific address against the current FEMA map, since San Antonio's own broader flood-risk research cites a roughly 19% chance of city buildings seeing significant flooding over 30 years today, projected toward 54% by 2050 under one climate-risk model (Augurisk/First Street aggregation, retrieved 2026-08-22) -- a citywide San Antonio-area figure, not confirmed as Universal-City-specific.
Key takeaways
- Universal City shares San Antonio's humid subtropical climate: hot, humid summers (highs near 96.6°F in August) and mild winters.
- Hail is the region's dominant, specifically documented severe-weather risk -- San Antonio logged its highest 10-year average of severe hail days on record from 2016-2025.
- The City of Universal City's own floodplain map shows most of the city in FEMA's minimal-hazard Zone X, with only limited Special Flood Hazard Areas -- a meaningfully lower flood profile than Kyle's documented Flash Flood Alley exposure elsewhere in this dataset.
- Hurricane exposure is not a meaningful risk this far inland; check a specific address against the current FEMA flood map regardless, given broader San Antonio-area flood-risk projections trending upward toward 2050.
