Daytime highs only move 19°C across the whole year (12–31°C), so timing matters far less here than rainfall does.
June gives you 15.1 hours of daylight against just 8.9 in December — a 6-hour difference in how much you can actually fit into a day.
July is the driest month at 30mm across roughly 2 wet days, while November peaks at 300mm.
July is almost as good as June, but usually quieter and cheaper. If your dates are flexible, it is the easier trip.
Kotor changes character completely through the year — June and December are effectively two different destinations. Pick the month that matches what you want to do, not the highest-rated one.
Ratings compare months within Kotor, not against destinations worldwide: five stars means the best time to be here, not that Kotor beats anywhere else. Tags describe what the conditions actually suit.

Each month in Kotor is described from long-run climate normals and then rated relative to the other eleven months in the same city. A five-star January in a cold destination means January is one of the best times to be there — not that it beats a Mediterranean summer.
| Factor | Weight | What it measures |
|---|---|---|
| Temperature | Described | Average daytime high and overnight low for the month, shown as measured rather than judged. |
| Precipitation | Described | Monthly millimetres and wet-day count, labelled as snow or rain/snow where temperatures make that the likely phase. |
| Sunshine & daylight | Described | Average daily sunshine hours and astronomical daylight length at mid-month, from the city’s latitude. |
| “Best for” tags | Derived | Applied only when the conditions genuinely support the activity — snow depth-friendly cold for skiing, 13–24°C and low rain risk for hiking, dark evenings at high latitude for aurora. A month with few strong use cases gets fewer tags rather than padded ones. |
| Star rating | Relative | Ranks the month against the other eleven months in the same city. Never a comparison between cities. |
Figures are long-run climate averages, not a forecast for a specific year. Where a month lacks sourced rainfall or humidity, the value is modelled from temperature range and rain frequency.
