How this match works

For each candidate city × month in our dataset, we compute the Euclidean distance between its average high, average low, and rain days and Helsinki's August values. Rain is weighted lower so one wet outlier doesn't override a strong temperature match. We then sort by closeness, keep only the best-matching month per city, and cap any one country at 2 results so the list isn't dominated by a single region.

The percentage above each card is a climate similarity score, not a recommendation — Helsinki's August might match Chicago's June on paper but feel very different in practice (humidity, altitude, urban heat, prevailing winds). Use these as a starting point for "if I love this, what else would I love?" — not as a one-to-one substitute.
