The playability score

Every SkyMatch response includes a playability_score — an integer from 0 to 100 representing how suitable weather conditions are for the requested activity during the booking window.
Score rangeRecommendationWhat it means
80–100safe_to_bookConditions look good. Low cancellation risk.
50–79proceed_with_cautionMarginal conditions. Worth flagging to the user.
0–49not_recommendedHigh chance of cancellation or poor experience.

​
What goes into the score

The score combines four weather factors, each weighted according to the sport parameter:
The chance of rainfall above 0.5mm/hr during the booking window. This carries the highest weight for most activities.
  • Low risk: under 20% chance of rain
  • Medium risk: 20–50% chance
  • High risk: over 50% chance
Average wind speed during the session in km/h. Thresholds vary significantly by sport — padel is highly wind-sensitive, while hiking tolerates stronger winds.
  • Low risk: under 20 km/h
  • Medium risk: 20–40 km/h
  • High risk: over 40 km/h
Extreme heat or cold reduces the score. Thresholds depend on activity type.
  • Outdoor fitness and padel: penalised below 6°C or above 33°C
  • Hiking: wider comfortable range (3°C–36°C)
  • Events: comfort-weighted, penalised below 10°C
A minor factor. Heavy overcast (over 85% cloud cover) slightly reduces the score for sessions longer than 90 minutes.

​
How the score is calculated

The formula is a weighted sum of factor sub-scores, normalised to 0–100: 
playability_score = (
  rain_sub_score   × rain_weight   +
  wind_sub_score   × wind_weight   +
  temp_sub_score   × temp_weight   +
  cloud_sub_score  × cloud_weight
) / total_weight
Weights are set per activity type. For padel for example: 
rain_weight  = 0.45
wind_weight  = 0.35
temp_weight  = 0.15
cloud_weight = 0.05

Using the score in your UI

The score is designed to be flexible — you can use it however fits your product: Simple recommendation badge 
if score >= 80 → show "✅ Recommended"
if score >= 50 → show "⚠️ Marginal"
if score < 50  → show "❌ Not recommended"
