Health Considerations in Texas
Texas's vast geographic and climatic diversity — from the humid Gulf Coast to the arid West Texas desert to the temperate Hill Country — means urgent care needs vary significantly by region, but extreme summer heat is a near-universal concern: Dallas, Houston, and San Antonio regularly record heat index values above 105°F from June through September. Cedar fever — an intense allergic reaction to mountain cedar pollen — affects millions of Central Texas residents from November through February, making it one of the most distinctive and severe allergy seasons in the country.

Should I go to urgent care or the ER in San Antonio?
