What is the UV index in Brighton in June?

June is the peak UV month in Brighton, with a daily-peak UV index of 6 (moderate). Standard sun protection — sunglasses and light SPF — is recommended.

How high can UV get in Brighton 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 6 (moderate), but the top 10% of days reach UV 7 (high) — and even higher. Months where the sunniest days routinely exceed the typical reading: March, May, June, July, August. Plan sun protection for the worst case, not the average.

Is air quality in Brighton bad for travelers?

PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 3 months: February, March, April. The worst month is March with a typical-day mean of 11 µg/m³ (moderate); on the worst 10% of days PM2.5 reaches 22 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.
