Houston, January 6, 2026

Houston is experiencing unusually warm weather, with January temperatures expected to reach record highs this week before a cold front brings a significant drop. From Tuesday through Thursday, temperatures could surpass 85 degrees—a record for this month—due to high pressure and southern winds. Participants of the Houston Marathon on Sunday will enjoy cooler conditions, with morning temperatures ranging between 40 to 50 degrees. Fog advisories remain in effect for areas near Galveston Bay, impacting travel in Southeast Texas.

Houston Experiences Record January Heat Ahead of Weekend Cool Down and Marathon

Houston is currently experiencing an unseasonably warm spell, with temperatures expected to reach record-setting highs for January from Tuesday through Thursday. This unusual warmth is forecast to give way to more typical winter conditions over the weekend as a cold front moves through the region, bringing ideal weather for the upcoming Houston Marathon.

On Tuesday, temperatures in Houston are projected to climb to between 83 and 85 degrees, likely surpassing the previous daily heat record of 80 degrees for January 6, set in 1989. The warmth could intensify on Wednesday, with highs possibly reaching the mid-80s, which would challenge the all-time January heat record of 85 degrees established on New Year’s Day in 2022. This extended period of heat is attributed to an upper-level ridge of high pressure situated over Mexico, combined with consistent southerly and southwesterly winds.

A significant change in weather is anticipated late Thursday into Friday with the arrival of a cold front. This front is expected to cause a considerable temperature drop, bringing highs down by approximately 20 degrees. Temperatures will then return to levels more typical for early January, with afternoon highs in the mid-60s and early morning lows in the 40s over the weekend. While there is a chance of isolated showers or spotty downpours, particularly across parts of Southeast Texas on Thursday and Friday, significant rainfall totals are not expected, with most areas likely receiving less than a quarter-inch.

For participants and spectators of the Houston Marathon on Sunday, January 11, the forecast indicates nearly perfect conditions. Morning temperatures for the marathon are predicted to be between 40 and 50 degrees Fahrenheit, rising into the low 50s by midday. Specifically, starting temperatures could range from 42 to 46 degrees under mostly clear skies, accompanied by light north winds of about 5 mph. The race day is also expected to feature low humidity levels and gentle breezes, further contributing to favorable running conditions.

Throughout this warm spell, areas of dense fog have been affecting Galveston Bay and the nearshore Gulf waters. Advisories for dense fog have been in effect, and patchy fog is also forecast for morning commutes across Southeast Texas through Thursday, which could impact travel.
