Today's briefing

Sydney's waking up to a chilly 8 degrees this morning, though it'll feel even colder at around 4 degrees with that 14 kilometre per hour wind, before warming to just 16 degrees by this afternoon. With no rain expected and a UV index of 4, today's looking like a clear but crisp winter's day across the city. Bundle up with layers and a windproof jacket if you're heading out, as that southerly breeze will make the cold feel sharper than the thermometer suggests. The weekend brings a slight warming trend, with Saturday reaching 16 degrees and staying mostly dry, but Sunday will turn cloudier with a 55 per cent chance of rain and a high of 17 degrees, so keep an eye out if you've got outdoor plans.

Sydney weather, explained

How to read the Sydney forecast

A good forecast is really three views at once. The current panel tells you what it feels like outside right now, which is what matters before you head out the door. The hourly strip is for planning the next part of your day: when the rain band arrives, when the wind picks up, when it is warm enough to walk. The seven-day outlook is for the week ahead, and it is most reliable in the first three or four days. Read it from the top down and you will almost always have what you need for Sydney.

Sydney weather and the coast

Sydney's weather is shaped by its coastal position. The ocean keeps overnight lows mild year-round compared with inland cities, while the sea breeze that rolls in from the east most summer afternoons brings welcome relief to the western suburbs that bake through the morning. North-easterlies in summer mean warm, clear days along the beaches. South-westerly changes in the afternoon are Sydney's version of a cold front: a sharp temperature drop and gusty winds that announce the end of a hot spell. The Blue Mountains to the west act as a barrier that sharpens these wind changes as they funnel through the gaps.

What the UV index means in Sydney

Sydney sits at 34 degrees south, which puts it in a UV band that surprises many visitors. On clear summer days the UV index regularly reaches 11 or above, meaning skin can burn in under ten minutes around midday. The index peaks at solar noon, not at the hottest part of the afternoon, so checking the number rather than judging by the temperature is the most reliable habit. Below 3 is low and you can be outside without extra protection. From 3 to 7 means sunscreen earns its keep. Above 8 means a hat, sunscreen and shade are all genuinely useful, not optional.
