When are crowds lowest in Korčula?

Search-interest seasonality (Google Trends 2021-2025) is lowest in January and peaks in June. Interest tracks both in-trip visitors and lead-time planners, so treat it as a "destination is on people's minds" signal rather than literal arrivals.

Which months in Korčula have good weather but fewer tourists?

May (climate 9/10, crowd index 0) and September (climate 9/10, crowd index 0) — shoulder months with above-average climate and below-median search-interest. Often the best value-for-weather trade.

How high can UV get in Korčula on the sunniest days?

Most days look like the monthly average, but on the sunniest ~1 in 10 days UV climbs higher than the mean suggests. June is the worst case: typical days average UV 8 (high), but the top 10% of days reach UV 9 (very high) — and even higher. Months where the sunniest days routinely exceed the typical reading: April, June, August, September. Plan sun protection for the worst case, not the average.

Is air quality in Korčula bad for travelers?

PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 6 months: January, February, March, August, October, December. The worst month is December with a typical-day mean of 11 µg/m³ (moderate); on the worst 10% of days PM2.5 reaches 18 µg/m³ (unhealthy for sensitive) and higher. People with asthma, heart conditions, or sensitive children may want to avoid these months or limit outdoor activity. Source: CAMS via Open-Meteo.
