How does Arncliffe’s weather compare with nearby Sydney weather?
Arncliffe sits just 10 kilometres south of the Sydney CBD, so its daily conditions closely mirror Sydney weather – expect similar temperature ranges and rainfall patterns. However, Arncliffe’s slight inland position can make it a degree or two cooler overnight than coastal suburbs. For a full Sydney outlook, see our Sydney Weather page. Meanwhile, Wollongong weather, about 80 kilometres south, often feels fresher due to stronger ocean influences.
