North Carolina Climate Data

Below is a collection of North Carolina Climate Data and outdoor design conditions. We included an North Carolina state average of each category at the bottom of the Manual J climate data table. We created this to allow an easy to use free resource for Manual J professionals to use on jobsites, in the field, and while calculating Manual J heat loss and heat gain reports. If you have a custom set of data from North Carolina we would consider adding to the North Carolina Climate Data table simply email it to plans@manualjs.com

We can also create a Manual J using climate data from the tables below. Email pdf plans, jobsite address, and square footage to plans@manualjs.com and we will get your North Carolina Manual J taken care of.
