In February 2021, Cy-Fair High School and the rest of the school district were shut down when Texas was hit with a snowstorm, caused by the February 2021 North American cold wave, that lasted from February 11 until February 20, which resulted in the 2021 Texas power crisis. It left more than 60 of the campuses throughout the district with massive water damage, some suffering with burst pipes caused by power outages and extremely low temperatures. The students were able to return to school on February 22, with the damages being fixed.
