Best Day Index
Fifty major destinations, one live ranking. Every city is scored 0–100 on today's conditions and given a straight answer: Go, Wait or Skip. The top of the list is where the weather is genuinely worth being outdoors today.
How the Best Day Index is calculated
Each city's rank comes from the Travel Score: a weighted composite of four sub-scores, each normalised to 0–100. Temperature comfort carries 40% because it dominates how a day outdoors actually feels. Rain risk carries 30%, wind 20%, and the WMO weather code 10%. The result is rounded to a whole number, and rain, shower or thunderstorm codes act as an absolute block: a wet day cannot be labelled a Go no matter how mild it is.
The index is deliberately willing to say no. Most weather sites hand you a temperature and leave the judgement to you. A ranking that never says Skip is not useful — the point of the index is that a low position is as informative as a high one.
Reading the verdicts
- Go (72–100): conditions support a full day outside. Book the tour, plan the hike.
- Wait (55–71): workable, but timing matters. Check the hourly view before committing.
- Skip (below 55): rain, wind or cold will define the day. Move outdoor plans if you can.

Frequently asked questions
What is the Best Day Index?
The Best Day Index ranks 50 major travel destinations by today's Weather Score — a 0–100 composite of temperature comfort (40%), rain risk (30%), wind (20%) and sky conditions (10%). The city at the top has the best conditions for sightseeing and outdoor plans right now.
How often does the ranking update?
Every time you load the page. Scores are computed live from the latest Open-Meteo forecast run (ECMWF, GFS and ICON models), so the ranking changes through the day as new model runs land.
What do Go, Wait and Skip mean?
Go means a score of 72 or higher with no blocking weather code — plans are safe. Wait means 55–71, or a decent score paired with rain: conditions are usable but timing matters. Skip means below 55 or active rain, showers or thunderstorms — move the plan to another day.
Why is a warm city ranked below a cooler one?
Because comfort is not the same as heat. A 34°C city with high rain probability scores below a stable 21°C city with clear skies. The index rewards conditions you can actually plan around, not peak temperature.
Can I see the full forecast for a city in the index?
Yes. Every city name links to its own Best Day page with a 14-day ranked forecast, activity verdicts, sunrise and sunset times, and a forecast confidence meter.
