Is a fixed awning practical, or do a sun sail or cantilever umbrellas make more sense? Of course, an awning works well for blocking the midday sun around the summer solstice, but if you’re sitting on the terrace in the afternoon, evening, or after work, the sun is already shining at a very different angle. Assuming a 4m (13 feet) awning—which I believe is usually the maximum—and a mounting height above the patio door of about 2.60 meters (8.5 feet), you get the following approximate values:
June 21, 12:30 pm => Shadow length 1.41 meters (4.6 feet), so 2.59 meters (8.5 feet) of the terrace shaded
June 21, 4:30 pm => 1.15 meters (3.8 feet) of the terrace remains in the sun
June 21, 5:30 pm => From this point on, the awning is completely ineffective
August 21, 12:30 pm => 1.83 meters (6 feet) of the terrace remains in the sun
August 21, 4:33 pm => From this point on, the awning is completely ineffective
September 1, 1:00 pm => Even at the solar noon, less than 1.60 meters (5.2 feet) of shading remains
Based on these considerations, a sun sail significantly larger than 4 meters (13 feet) might be more practical, which could have a deep corner on the west side. Alternatively, cantilever umbrellas might be a better option since they can be adjusted flexibly.
What are your thoughts?

In my opinion, a south-facing terrace can be effectively shaded with an awning. For a west-facing terrace with open land and no trees or buildings nearby, I see potential challenges.Any suggestions?
What are your plans?
