Scoring Methodology

What Is the GO Score?

The GO Score is a composite score from 0 to 100 that measures how favorable conditions are for traveling to a specific destination right now. It combines five real-time factors into a single number — the higher the score, the better the travel window.

Scoring Factors & Weights

Each destination's GO Score is calculated from five equally important but differently weighted factors:

Data Sources

• Flight prices — Aggregated from public travel search APIs
• Hotel prices — Aggregated from public travel search APIs
• Weather forecasts — Open-Meteo (open-source weather API)
• Currency rates — Frankfurter (European Central Bank data)
• Public holidays — Nager.Date
• Events & festivals — Ticketmaster Discovery API
• Air quality — OpenAQ
• Country information — REST Countries and GeoDB Cities

Update Frequency

All scores are recalculated daily at 06:00 UTC. Flight and hotel prices, currency rates, weather forecasts, and event data are refreshed as part of this daily update cycle.

Score Tiers

What the GO Score Is NOT

• Not a safety rating — The GO Score does not assess political stability, crime rates, or health risks. Always check government travel advisories before traveling.
• Not a guarantee — Scores reflect current conditions based on available data. Prices, weather, and events can change at any time.
• Not influenced by affiliate revenue — Affiliate relationships have zero effect on scores or rankings. See our Affiliate Disclosure for details.

Limitations

• Prices are approximate and may differ on the provider's site at the time of booking
• Weather data is probabilistic — forecasts become less accurate beyond 7 days
• Events can be cancelled or rescheduled after our data is collected
• Currency rate changes are measured year-over-year and may not reflect very recent fluctuations
