Recent National Weather Service forecasts for Houston Intercontinental Airport project a high near 90°F on October 15 under mostly sunny to partly cloudy skies with light southeast winds and minimal rain chances. This aligns with the market's leading 88-89°F and 90-91°F bins, reflecting model consensus on modest cooling from recent 92-94°F readings amid a strengthening high-pressure ridge. Historical October averages near 85°F provide context, while the absence of tropical moisture or strong frontal passages supports limited upside risk to the upper 90s. Updated model runs and official briefings through October 14 will refine the exact maximum.
