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.
