Clear Skies and Cool Air to Start the Day

Houston will wake up to chilly conditions, with early morning temperatures near 35°F. Because skies stay clear overnight, heat will escape quickly. As a result, residents should expect a crisp start during the first few hours of daylight. Light NNW winds around 12 mph will add to the cool feeling but will not create hazardous conditions.

Sunny and Mild Afternoon Ahead for Houston

Throughout the afternoon, the forecast calls for abundant sunshine and stable weather. High temperatures will reach roughly 56°F, which is slightly warmer than the seasonal average. Winds will remain NNW but light, and occasional gusts may approach 24 mph. Even so, these gusts remain well below any advisory thresholds.

Cloud cover stays at 0%, giving the city a bright and clear sky all day. These conditions will help warm the region after the morning chill. With no rain in the forecast, roads and outdoor facilities will stay dry and accessible.

Evening and Air Quality Outlook

Temperatures during the evening will settle near 56°F before dropping back to the low 50s overnight. Skies remain clear through the night, offering ideal visibility for stargazers and late-night commuters. The stable high-pressure system over the region also supports good air quality. No alerts or concerns are expected for sensitive groups.

Because humidity stays low, the evening air will feel crisp but comfortable. Residents planning to be outdoors should still bring a light jacket, especially after sundown.
