Climate:
Being in the Southern Hemisphere Australia's seasons are at opposite times to those in the northern hemisphere. December to February is summer; March to May is autumn; June to August is winter; and September to November is spring. The climate of Sydney is humid subtropical shifting from mild and cool in winter to warm and hot in the summer. There are no extreme seasonal differences as the weather is moderated by proximity to the ocean, but there are more contrasting temperatures recorded in the inland western suburbs. Despite the fact that there is no distinct dry or wet season, rainfall peaks in the first half of the year and is at its lowest in the second half. Precipitation varies across the region, with areas adjacent to the coast being the wettest. The city receives around 20 thunderstorms per year.
