Wind is an issue, use of fog spray is not effective as a interim curing method.

Lowering concrete temperature is an effective way to reduce evaporation rate. If this method is used to reduce the evaporation rate below 0.200 lbs/sf/hr, the concrete temperature input in this template becomes the maximum concrete temperature allowed for the pour unless a change in conditions allows a higher temperature. Weather conditions should be monitored and evaluated frequently throughout the pour to ensure evaporation rate is controlled.
