Equable usually describes either climate or personality. The word seems to be used less today than in decades past, maybe because the personality type is less admired than it used to be. A steady, calm, equable personality may not produce much excitement but usually makes for a good worker and a good parent, and maybe even a longer life. In the words of the poet Robert Service: "Avoid extremes: be moderate / In saving and in spending. / An equable and easy gait / Will win an easy ending".
