Abstract: Provided are louver blade, louvered roof, and viewing shelter. Drainage groove is arranged on one side of body of louver blade; and includes groove wall located on outer side of body. Baffle plate is arranged on top of groove wall. When body is arranged horizontally, top end of groove wall is not higher than top surface of louver blade. Baffle plate can switch between natural and stressed states. Top end of baffle plate in natural state is higher than top end of groove wall, and has height that can be reduced in stressed state. Louvered roof includes shelter frame and multiple louver blades. When multiple louver blades are closed on shelter frame, other side of one louver blade relative to drainage groove presses against baffle plate of adjacent louver blade. Baffle plate switches to stressed state. When louver blades rotate to open, baffle plate switches to natural state.
