Overview of Today’s Conditions

Temperatures reach a comfortable daytime high of about 81°F, with a morning low near 66°F. The afternoon holds steady in the upper 70s, and evening temperatures dip into the low 70s before reaching an overnight low of about 69°F. Because the sky stays almost completely overcast, sunlight will be limited. These clouds help keep temperatures consistent throughout the day.

Winds move from the south-southwest at about 13 mph. Gusts may reach 26 mph, though no severe wind impacts are expected. Even so, elevated gusts could make driving on open roads feel slightly breezy. Thankfully, the risk of thunderstorms or heavy rain remains low today.

Clouds, Humidity, and Air Quality

Cloud cover reaches nearly 100%, providing a blanket of gray from morning into night. Conditions may feel a bit humid even if actual precipitation stays away. Since humidity levels remain elevated, residents may want to keep indoor air conditioning or air circulation running to maintain comfort.

Air quality appears stable this morning. With no major pollution events or stagnation expected, outdoor activities should be safe for most people. The cloud-heavy sky may make the day feel cooler than actual temperatures suggest, but the warm Gulf air remains present.

Impacts on Daily Plans

Although the weather stays quiet, today's conditions can affect schedules in subtle ways. Morning commuters will deal with low light due to overcast skies, so drivers should use headlights even after sunrise. Outdoor workers may appreciate the moderated temperatures, as afternoon highs in the low 80s keep heat stress fairly low.

Because winds may occasionally gust, people cycling, jogging, or working near loose materials should stay aware. Families with outdoor activities can comfortably continue their plans, but cloud cover may reduce visibility for photography or aviation-related hobbies.

The next few days could bring increased rain chances as a weak disturbance approaches the Texas coast.

For now, enjoy a calm, gray, and warm day across Houston. Keep light layers handy and stay weather-aware as patterns evolve through the week.
