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 Valletta?
Search-interest seasonality (Google Trends 2021-2025) is lowest in June and peaks in November. 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 Valletta have good weather but fewer tourists?
May (climate 10/10, crowd index 19) and June (climate 10/10, crowd index 0) — shoulder months with above-average climate and below-median search-interest. Often the best value-for-weather trade.
What is the UV index in Valletta by month?

How high can UV get in Valletta 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 9 (very high) — and even higher. Months where the sunniest days routinely exceed the typical reading: March, April, May, October, November. Plan sun protection for the worst case, not the average.
Is air quality in Valletta bad for travelers?
PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 8 months: February, March, April, May, June, July, August, October. The worst month is July with a typical-day mean of 14 µg/m³ (moderate); on the worst 10% of days PM2.5 reaches 24 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.
