The invention relates to an annular butt joint structure of a fuselage with weatherproof composite skin. The annular butt joint structure is characterized in that a front fuselage skin body and a rear fuselage skin body are respectively borne on upper end faces of two metal machining frames, the metal machining frames are in butt joint, a boss structure is arranged at the position of the joint, the fuselage skin bodies are located on the rear side of a boss to form step difference with the boss, and a gap between the boss and the fuselage skin bodies is filled with sealant. The boss is arranged on the upper end faces of the metal machining frames, wind erosion to the end face of the composite skin can be avoided, protection means of the end face of the composite skin is simplified, and assembling cost of final assembly and partial assembly is lowered.
