South Texas International Half Marathon
Race Day Weather
Comfortable temps, big temp swing, moderate wind
Starting at 64°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temps will climb significantly to 89°F by later miles, so expect fading conditions as the race progresses. Moderate winds around 12mph may affect pacing on open sections of the course. Moderate humidity at 72% is worth noting for effort level, especially in later miles.
