Summer Water temperatures on the sheltered inside of the Bay are generally between 22-25C at the northern (Melbourne City) end, between 20-23C in the middle of the eastern side, 20-22C in the Southern Bay and, as might be expected in a lower range on the unprotected Southern seaward side. Given Melbourne’s southerly position in Australia winter, temperatures can be significantly lower but as compensation you might be lucky enough to see a penguin or two.
