Re-score for me — drag the dial — every chart recolours live for your heat & sea limits 27°C · sea 29°C
Default 27 °C is the upper edge of the Holiday Climate Index "ideal comfort" band (Scott, Rutty, Amelung & Tang, 2016). Above this, most warm-tourism travellers report measurable discomfort.
Default 29 °C is the Beach Climate Index "bathtub" line (Morgan et al.) — where the sea stops being refreshing and starts feeling like a warm bath.

When are crowds lowest in Milos?
Search-interest seasonality (Google Trends 2021-2025) is lowest in October and peaks in August. 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 Milos have good weather but fewer tourists?
May (climate 10/10, crowd index 48) and September (climate 10/10, crowd index 37) — shoulder months with above-average climate and below-median search-interest. Often the best value-for-weather trade.

How high can UV get in Milos 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. May is the worst case: typical days average UV 7 (high), but the top 10% of days reach UV 8 (very high) — and even higher. Months where the sunniest days routinely exceed the typical reading: February, April, May, November. Plan sun protection for the worst case, not the average.
Is air quality in Milos bad for travelers?
PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 1 month: July. The worst month is July with a typical-day mean of 11 µg/m³ (moderate); on the worst 10% of days PM2.5 reaches 15 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.
