The live forecast above shows Sydney’s 14-day outlook, with daily maximum and minimum temperatures and rainfall chances. Across the fortnight, expect a mix of mild days and cooler nights typical of late autumn, with a few showers possible early and again around day 10–12.
What does the 14-day forecast for Sydney actually tell me?
It gives a general trend rather than exact day-by-day certainty. For example, if the live forecast above shows 25°C on day 3 and 18°C on day 8, you can plan for a warmer mid-week window followed by a cooler period. The Bureau of Meteorology (BOM) uses ensemble models to produce this range, so confidence is highest in the first week and drops sharply after day 10.
How reliable is a 14-day forecast, really?
At this range, the day-to-day detail has low precision – a predicted 22°C may end up being 19°C or 25°C. What you can rely on is the broad pattern: whether a cooler change is coming, if there’s a wet spell forming, or if a stable high-pressure ridge will bring fine days. For Sydney, the 14-day outlook helps you see the shift from autumn to early winter conditions, such as increasing westerly winds and overnight lows dipping below 10°C in the second week.
Does the 14-day forecast update every day?
Yes – the live forecast above refreshes multiple times daily from BOM and other models. For the most current picture, check the Sydney Weather page for today’s observations and the next few days.
Can I get a 21-day or 30-day forecast for Sydney?
Longer-range outlooks (21-day, 28-day, 30-day) exist but are experimental and very low confidence. For a practical view, stick to the 14-day forecast and supplement with the Weather 10 Days page for higher accuracy.
What’s the difference between the BOM 14-day and other providers like AccuWeather?
BOM’s 14-day forecast uses Australian models tuned to local geography (e.g. Sydney Harbour effects). International sites like AccuWeather blend global models, so you may see a slight difference on the same day. Always cross-reference with Bureau of Meteorology for official warnings.
