What January feels like in Sydney
Summer peaks in January: no month in Sydney is warmer (Sydney is in the southern hemisphere, so the seasons run opposite to Europe and North America). Days are warm enough for short sleeves, and time outdoors is easy. Little changes after sunset — nights stay warm, only slightly below the daytime level. High humidity makes the heat feel heavier and sticky, especially on still afternoons.
Rain in Sydney in January
Showers are a regular feature, arriving about one day in 3. Each rainy day adds about 7.6 mm (0.3 in), a proper wetting rather than a sprinkle. That is close to Sydney's typical rain per wet day for the whole year (about 7.7 mm). It is among the three wettest months of the year.
