San antonio weather forecast 10 days

As of October 16, 2026, the National Weather Service has issued a long-range forecast for San Antonio, indicating that the region will remain under the influence of a persistent high-pressure ridge for the next ten days. Residents should prepare for unseasonably warm temperatures, with daily highs consistently reaching the upper 80s and low 90s, significantly above the historical average for mid-October. The forecast shows no signs of significant precipitation, extending the current dry spell that has affected South Texas throughout the month. While mornings will offer a brief respite with temperatures dipping into the mid-60s, the lack of cloud cover will lead to rapid heating by midday. Meteorologists are monitoring a weak cold front expected to approach the region toward the end of the ten-day period, though current models suggest it will likely stall before reaching the city, providing only minimal relief. The extended dry conditions have prompted local officials to remind residents to remain vigilant regarding fire safety and water conservation efforts as the region continues to experience this prolonged period of heat and aridity.
