The temperature effect for the intensity of μ-mesons at sea-level is investigated by taking π-μ decays into account. The positive temperature coefficient is calculated by paying special attention to the difference in the attenuation mean free path of the N-component and the absorption mean free path of π-mesons and to the atmospheric depth which gives main contributions to the coefficient. The magnitude of the coefficient is obtained as 0.05% / °C and the depth of main contributions is found to be 200 mb. Influence of heavy mesons is qualitatively discussed
