How scores work

A score always lands in one of four tiers. Each tier has its own mark and word, so you never have to tell it by colour.

1. 91

   Epic

   85–100

   Worth flying for. The strongest alignment across tracked factors.

2. 72

   Good

   65–84

   Worth a short hop. Several important factors align, with some tradeoffs.

3. 57

   Fair

   50–64

   Rideable. A mixed window that warrants closer local review.

4. 31

   Poor

   0–49

   Skip. Tracked factors do not support a strong window.

A dash (—) means we have no forecast for that day, which is not the same as Poor. When a spot is Poor outside its best months, the sheet shows its season instead, for example “Off season · best Dec–Feb”.

Each sport has a short list of factors, such as fresh snow or swell period. A factor earns points when the forecast meets its threshold, up to a fixed maximum, and the points add up to the score. The tables under Sport by sport list every factor.

Two rules can hold a score down:

• Wind safety limits. For windsurfing, kitesurfing, paragliding, wingsuit flying and sailing, wind above the sport’s limit holds the score at 20 (Poor).
• Partly tracked sports. For scuba diving and whitewater, no forecast covers the things that matter most (river flow, underwater visibility), so the score stops at 84 (Good) and is never Epic.

We only look up cached fares for a spot when its sport’s peak conditions are met right now. For most sports that means a score of 85 or more. Powder skiing, snowboarding, windsurfing and surfing use their own rule instead, and the partly tracked sports never qualify. Everywhere else, the flight link opens a search on our partner’s site without a price.

Powder skiing

When all of these hold right now: fresh snow 15 cm or more in 24 hours; snow temperature -2°C or colder.

Snowboarding

When all of these hold right now: fresh snow 15 cm or more in 24 hours; snow temperature -2°C or colder.

Windsurfing

When all of these hold right now: sustained wind 15 knots or more; gust stability gusts no more than 1.4× sustained wind; coast-relative angle side-shore or side-onshore (0°–110° relative angle).

Surfing

When all of these hold right now: swell height 1.5 m or higher; swell period 10 seconds or longer; offshore wind under 15 knots and more than 110° from the coastline bearing.

Kitesurfing

When the score is 85 or more (Epic), with wind under the safety limit.

Mountain biking

When the score is 85 or more (Epic).

Climbing

When the score is 85 or more (Epic).

Scuba diving

Never: this sport is partly tracked, so it can't reach Epic.

Whitewater

Never: this sport is partly tracked, so it can't reach Epic.

Paragliding

When the score is 85 or more (Epic), with wind under the safety limit.

Wingsuit flying

When the score is 85 or more (Epic), with wind under the safety limit.

Sailing

When the score is 85 or more (Epic), with wind under the safety limit.

Points shown are maximums. Each spot page shows the reading we used and the points it earned.

Forecasts come from OpenWeather, Open-Meteo (swell and snow) and Tomorrow.io. We collect them on a schedule, score every spot and store the result. Pages read that stored result; they never ask a weather service while you wait.

That makes every score a few minutes to a few hours old:

• Up to 3 hours old, a score shows normally with its age (“Updated 52 min ago”).
• Older than that, it’s marked as an older forecast.
• Past 48 hours, we hide the score rather than show a stale one.
• Fare checks need a reading under 3 hours old (1 hour for Tomorrow.io readings).

• Forecasts and modeled conditions can differ from conditions at the site.
• Precipitation evidence labels the provider-specific rate: OpenWeather values are normalized to in/hr, while Tomorrow.io values remain mm/hr to preserve the accepted legacy calculation.
• The score is guidance, not a safety forecast; check local reports and official warnings before travel or participation.

• Windsurfing, kitesurfing, paragliding, wingsuit flying and sailing have wind safety limits. Above them the score is held at 20 (Poor), so gale-force wind can't read as a top score.
• Scuba diving and whitewater are scored only on what we can measure and stop at 84 (Good). They can't reach Epic until river flow and underwater visibility are tracked.
• Gust readings below the sustained wind speed are raised to the sustained speed before scoring.
