A monthly weather forecast gives a broad look at temperature and rainfall trends for the next 28 days, using computer models and climate history. The live forecast above shows Sydney’s expected range for the month, including average conditions and possible extremes.
What does the monthly forecast tell you?
The forecast outlines likely temperature bands and rainfall totals, not precise daily details. For Sydney, it indicates whether the month will be warmer or cooler than average, and whether rainfall is above or below typical levels. Use it for general planning, not for day-to-day decisions. For a more detailed 28 day weather forecast Sydney, check the BOM website.
How does a 28-day outlook compare with longer forecasts?
A 28-day forecast is more detailed than a seasonal outlook but less precise than a 7-day prediction. It is updated regularly by the Bureau of Meteorology. For other cities you can find a monthly weather forecast Melbourne, a Brisbane monthly weather forecast, a monthly weather forecast Gold Coast, and a monthly weather forecast Sunshine Coast. For daily updates, visit the Sydney Weather page. For warnings, see our Severe Weather Warning page.
How often is the monthly forecast updated?
The Bureau of Meteorology issues a new climate outlook every Thursday. This page reflects the latest available data from that update.
Can I use the monthly forecast for holiday planning?
Yes, for general weather trends. But check a 7-day forecast closer to departure. Monthly forecasts are also available for Melbourne, Brisbane, Gold Coast, and Sunshine Coast.
What is the difference between a 28-day and a 3-month outlook?
A 28-day forecast covers the immediate month ahead, while a 3-month outlook shows broader seasonal trends. For example, a 3 month weather forecast Brisbane AccuWeather alternative is available from BOM.
