Hot weather concreting is any period of high temperature in which special precautions need to be taken to ensure proper handling, placing, finishing, and curing of concrete. The exact temperature where special precautions should be taken varies. According to Jack Holley, a concrete veteran of 45 years, 80°F (27°C) is a good benchmark to use.
