Nebraska Climate Data

We offer an Nebraska Manual J for $79 in 4-6 hours.  We can also offer Nebraska Manual S $79 and Nebraska Manual D $99.

Below is a collection of Nebraska Climate Data and outdoor design conditions. We included an Nebraska 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 Nebraska we would consider adding to the Nebraska Climate Data table simply email it to

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