Travel planning FAQ
Quick answers to the weather questions you ask the most.
The monthly score is a 0-100 weather suitability signal for that destination. It is location-relative, so it is designed for comparing months within Sydney, not for cross-city comparisons.
Scores combine long-term monthly normals and historical event rates from a 30-year baseline. The model blends Comfort (30%), Rain reliability (25%), Extreme risk (25%), and Outdoor (20%) into a single monthly value.
Comfort measures typical feel and stability; Rain reliability measures wet-day frequency and rain intensity; Extreme risk captures heat, cold, wind, and related disruption pressure; Outdoor measures day-to-day usability for outdoor plans. Higher values indicate better conditions within each component.
The Monthly planning overview summarizes month-by-month planning stability and trade-offs. Months are grouped into four bands: Strong window, Mixed, Trade-offs, and Higher disruption.
