About the KHOU Weather Station
The KHOU ASOS is located at William P. Hobby Airport in southeast Houston, approximately 7 miles from downtown and about 30 miles from the Gulf of Mexico. At just 46 feet elevation, this is one of the lowest-lying major airport markets.
Hobby's proximity to the Gulf of Mexico and position within the urban core of Houston creates a distinctive microclimate. The station often records higher humidity and slightly moderated temperature extremes compared to the more inland Bush Intercontinental Airport.

Houston Climate & Temperature Patterns
Houston experiences a humid subtropical climate (Koppen: Cfa) with hot, humid summers and mild winters. Gulf of Mexico moisture dominates the weather, creating high humidity year-round.
Key Climate Factors:
Gulf Moisture: Persistent moisture from the Gulf creates high humidity and feeds frequent showers and thunderstorms. This moisture also moderates extreme heat somewhat.
Sea Breeze: A Gulf sea breeze often develops during summer afternoons, providing modest cooling to areas near the coast.
Tropical Weather: Houston is vulnerable to tropical storms and hurricanes from June through November. These systems bring clouds, rain, and dramatically affect temperatures.
Mild Winters: Cold fronts push through regularly in winter but arctic air is quickly moderated by Gulf warmth.

Winter (December - February):
Mild with average highs in the low-to-mid 60s°F. Cold fronts bring temperature drops but rarely severe cold. Freezing temperatures occur just a few times per year.
Spring (March - May):
Warming temperatures with increasing storm activity. Severe weather is possible as Gulf moisture clashes with frontal systems.
Summer (June - August):
Hot and humid with average highs in the low-to-mid 90s°F. High humidity makes heat feel more oppressive. Afternoon thunderstorms are common.
Fall (September - November):
Peak hurricane season through October. Otherwise gradually cooling with pleasant temperatures by late fall.

Houston-Specific Trading Tips
Track Gulf Moisture: Dew points above 70°F indicate heavy moisture that can limit extreme heat but also prevent significant cooling.
Sea Breeze Impact: The Gulf sea breeze can limit afternoon highs at Hobby compared to inland Houston locations.
Tropical Threats: During hurricane season, approaching tropical systems dramatically affect temperatures with increased clouds and rain.
Cold Front Timing: As with other Texas markets, cold front timing determines daily highs.
