I have a small open area, it's like a small balcony. The issue is that I get wet when it rains.
I ended up buying a regular tarp that covers this open area, and it works well. The issue is that this material isn't breathable, plus it also blocks the sunlight. It tends to get a little warm with the tarp.
Is there any type of material that will let sunlight and air through, but is tightly knitted so that it blocks rain drops?
Just wanted to add that the fabric or mesh will be at a slope, something like this. Also, this "fabric" will never be hit by direct rain. It also doesn't have to be waterproof, it just needs to bead and run off.
Also wanted to add that I usually use this area at night, so ideally, I would like to be able to see some of the sky while being protected from rain. I can't see anything with the tarp, plus it gets slightly warm at night.

Sunlight, no. "Breathable", yes. That's what "Gore-tex" fabric is famous for. They were the first / biggest, but now many other suppliers have released similar breathable waterproof fabrics made from PTFE (a.k.a. "teflon") fibers. I don't think however that Gore-tex makes anything clear or even opaque.
And go get a second mortgage on your house if you want a large tarp made of it; the cost is very very high.
