How does one determine runway orientation without a local wind rose? We are planning to establish new airport, but then we have no wind rose analysis of the location.

How can we predict what's the right orientation for the runway that satisfies the 95.
Assuming that you are not bound by local topography and thus can build the runway in, theoretically any direction you like, there are a few things you can do. First, you could set up a small weather station and record some data. You could then use this data to determine your direction. You can also use a site like this one to see the historical wind/weather data in the area. This will help you get an idea of the prevailing winds at near by.
