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.

Frequently asked questions about visiting Barcelona
When is the best time to visit Barcelona?
June is the highest-scoring month (9/10 on the Holiday Climate Index). Typical conditions: 19–26°C (8 rainy days). The top three months by score are June, May, October.
What is the worst time to visit Barcelona?
August is the lowest-scoring month (7/10, capped by extreme heat). Typical conditions: 22–29°C (6 rainy days).
Is Barcelona too hot in summer?
2 months (July, August) trip the heat deal-breaker in our scoring: apparent temperature crosses the comfort cap, so even with clear skies and low rain the score is held down. Plan around it if heat tolerance is low.
When are crowds lowest in Barcelona?
Search-interest seasonality (Google Trends 2021-2025) is lowest in June and peaks in April. 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 Barcelona have good weather but fewer tourists?
June (climate 9/10, crowd index 0) and July (climate 8/10, crowd index 27) — shoulder months with above-average climate and below-median search-interest. Often the best value-for-weather trade.
What is the UV index in Barcelona by month?
UV peaks at 8 (high) in July and is lowest in December at 1 (low). Monthly peak values: Jan 2, Feb 2, Mar 4, Apr 6, May 7, Jun 8, Jul 8, Aug 7, Sep 5, Oct 4, Nov 2, Dec 1.
What is the UV index in Barcelona in July?
July is the peak UV month in Barcelona, with a daily-peak UV index of 8 (high). Apply SPF 30+, wear sunglasses, and seek shade during midday hours.
How high can UV get in Barcelona 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. July 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: February, March, April, June, July, August, September. Plan sun protection for the worst case, not the average.
Is air quality in Barcelona bad for travelers?
PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 12 months: January, February, March, April, May, June, July, August, September, October, November, December. The worst month is February with a typical-day mean of 19 µg/m³ (unhealthy for sensitive); on the worst 10% of days PM2.5 reaches 34 µg/m³ (unhealthy) 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.
