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.

Months where the sunniest days routinely exceed the typical reading: April, June, August, September. Plan sun protection for the worst case, not the average.

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.
