Houston Heat Index Tops 90 Despite Modest Highs

The heat index in Houston, Texas, is projected to reach 90 degrees Fahrenheit (32 degrees Celsius) on Sunday, November 1, according to AccuWeather. The actual air temperature will peak at 82 degrees Fahrenheit (28 degrees Celsius) during the day. Conditions will remain partly cloudy throughout the forecast period.

Temperatures will drop to a low of 70 degrees Fahrenheit (21 degrees Celsius) overnight. The chance of precipitation stays low, ranging between 1 percent and 7 percent for the day. This limited rainfall probability suggests a dry start to the month for the metropolitan area.

Wind speeds will remain gentle, with gusts reaching a maximum of 5.59 miles per hour during daylight hours. Nighttime gusts are expected to slow to 4.35 miles per hour. The sun will rise at 6:35 a.m. and set at 5:35 p.m. on Sunday.

The high heat index is driven by persistent humidity levels. Relative humidity in Houston typically fluctuates between 50 percent and 90 percent due to the city's proximity to the Gulf of Mexico. This moisture content makes the air feel warmer than the thermometer indicates.

Houston experiences annual rainfall totals of approximately 39 inches. The city's average temperature ranges from 49 degrees Fahrenheit (9 degrees Celsius) in winter months to 90 degrees Fahrenheit (32 degrees Celsius) in summer. June, July, and August record the highest temperatures, while December, January, and February are the coldest months.

Air quality in the region is generally good, though industrial emissions from local refineries can cause fluctuations. Summer months often see elevated ozone levels, a condition that can affect residents with respiratory conditions. The city faces moderate risks from natural disasters, particularly hurricanes and flooding given its low-lying geography and coastal location.

Tornadoes occur less frequently than hurricanes or floods in Houston but remain a potential hazard. Local emergency protocols are in place to activate during such events. The combination of high humidity and moderate wind speeds defines the typical November weather pattern for the Gulf Coast city.
