Site analysis isn't a sheet of diagrams about sun, wind and traffic. It's observation, and the way we teach it, observation is the beginning of the whole project: the entire phase of research, analysis, and experiencing the site and the project. Students ask me again and again how to do it, very few master it, and university doesn't teach it.
What students usually produce
A sun path, a wind rose, traffic arrows, a zoning map, some photos. It's the same template every time, done because it's required, and then put aside when the "real" design starts.
Why that isn't enough
Those diagrams record facts about the site. They don't tell you what the project should be. Analysis without observation gives you data without an idea, which is why so many concepts end up disconnected from the site they're meant to respond to.
Observation is where the project begins
Good site analysis is where your concept starts. It's research, analysis and experience together: being on the site, understanding what is there and what it means, and carrying that into every decision after it. Done well, the rest of the project grows out of it.
Why it takes practice
It sounds simple, and it isn't. Observation is a skill, and like any skill it improves with practice and precise feedback. That's why students keep asking how to do it, and why it's one of the first things we teach.
