Frequently asked questions
Which months are highest-ranked for San Diego?
What does the monthly score represent?
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 San Diego, not for cross-city comparisons.
How are the monthly scores calculated?
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.
What do Comfort / Rain reliability / Extreme risk / Outdoor components mean?
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.
What do "Months ranked by travel style" results mean?
What does the "Monthly planning overview" section show?
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.
What does the "Weather risks" panel represent?
This panel summarizes historical weather-event rates for the currently selected month at this location. It is baseline-only and based on a 30-year climate record, not a date-specific forecast.
Do these rankings consider crowds, prices, or events?
No. Rankings on this page are weather-only and based on climate baselines plus historical event patterns.
When should I use Trip Planner instead of this page?
Use this page for month-level baseline comparisons. Use Trip Planner for exact dates because it layers baseline signals with forecast data and threshold-based checks.
