The weather when you can actually use an umbrella is actually a pretty narrow window. It needs to be wet (obviously) enough for you to need protection, but not windy. Bearing in mind rain often does come with the wind, this is harder than it seems.
You could chance it, of course, if you really need to stay dry. You do run the risk of the same thing happening to you as to the guy in the picture. He forgot to check the wind speed, and now he’s both wet and has to walk around with a stick on a handle.
