Also, as described in ACI306, cold weather is defined as a period when, for more than 3 consecutive days, the following conditions exist: 1) the average daily air temperature is less than 40F (5℃) and 2) the air temperature is not greater than 50F (10℃) for more than one-half of any 24-hr period. The average daily air temper
