Even the best models commonly available will only operate at a 3km resolution, which realistically isn't that much more useful than a 10km or 20km grid for ageostrophic winds (wind not affected by the ground). A model might show you have 8kt winds out of the SSE, but things like water, treelines, hills, etc. could have a large impact on a golf ball. It'd be easy enough to look at the forecast for a 3km model like the HRRR, but the challenging part would be guessing at how the various features on a course interact with that forecast.

Right, I talked about this below, but really the main thing is just knowing the which of the 16 labeled directions the wind is coming from, and then checking back every few holes if possible, and then make arrows on the course map with that overall direction. And yes, trees and hills totally have an impact, but the main impact is the difficulty of having a very in tune knowledge of where the wind above the trees and hills is blowing. If you're hitting a normal full shot, the ball flight will be (usually) only affected by the standard wind direction. Again of course, there are gusts that make that difficult to time a shot, and ball flight and shot type make a difference as well, but knowing and trusting the overall direction would be really helpful.
