Derating: Outdoor Temperatures for Various U.S. Cities - Table

Design Temperatures For Various U.S. Cities

The following table indicates the 2% design temperature (averaged for June-August) for various cities; and the various temperatures inside conduit on rooftops exposed to direct sunlight.

The first column represents the ASHRAE 2% design temperature1. The second through fifth column is the resultant ambient temperature inside the conduit - unloaded2. It is the temperature the wire is subjected to.

The 6th column is the maximum dry-bulb temperature recorded for that city, based on 30 years of weather data.

Click on the state links below to see the outdoor temperatures for cities in that state.
