How this holiday fit is calculated
Climate bands use monthly day-and-night means: warm 20–26°C, mild 12–20°C, cool 0–12°C. Temperature fit is 100 in the chosen band, falling 10 points per degree outside it, down to zero. This is our disclosed preference rule, not a NASA destination rating.
Documented selected features receive a presence match of 100, not a quality score. Overall fit is the weighted mean of supported priorities. Missing evidence reduces coverage, not fit. Rain is context only. No live prices, crowd ratings, family-suitability scores or transport times are invented.
The website and browser app use the same expanded-catalogue API. The reviewed collection remains available separately. NASA POWER climate documentation; coordinates from the existing catalogue and Open-Meteo / GeoNames (CC BY 4.0).
What nearby evidence can—and cannot—tell you
Open beach and ski-resort identities come from Wikidata (CC0), linked to GeoNames places (CC BY 4.0). Search uses named beaches within 25 km and ski resorts within 50 km, measured in a straight line—not road travel time. Inland beaches do not prove sea access. Ski areas do not prove summer trails, snow or operating lifts.
Only a directly reviewed destination inherits its documented cultural and local features. A nearby climate reference is limited to 25 km within the same country, labelled with its source place and distance; mountain elevation and local conditions can still differ. Nearby towns do not inherit museums, restaurants or safety ratings.
Expanded results are ranked across the filtered catalogue on the server before a bounded result list is returned. Importance weights, concrete selections and trip-night-weighted monthly climate determine partial fit. The expanded score multiplies partial fit by evidence coverage; unreviewed evidence strength is capped at 60%, with open-feature-only records at 45%. Below 35% coverage, no score is shown. These are conservative product rules, not probabilities or provider ratings.
The catalogue is incomplete and not a claim to list every beach or resort worldwide. Specific beach surfaces, safe swimming, budgets, accommodation and exact-date must-haves remain unverified until appropriate evidence exists.
