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 Cádiz
When is the best time to visit Cádiz?
May is the highest-scoring month (10/10 on the Holiday Climate Index). Typical conditions: 16–25°C (4 rainy days). The top three months by score are May, June, September.
What is the worst time to visit Cádiz?
August is the lowest-scoring month (7/10, capped by extreme heat). Typical conditions: 21–30°C (0 rainy days).
Is Cádiz 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 Cádiz?
Search-interest seasonality (Google Trends 2021-2025) is lowest in January 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 Cádiz have good weather but fewer tourists?
May (climate 10/10, crowd index 0) 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 Cádiz by month?
UV peaks at 9 (very high) in July and is lowest in December at 2 (low). Monthly peak values: Jan 2, Feb 3, Mar 5, Apr 7, May 8, Jun 9, Jul 9, Aug 8, Sep 7, Oct 5, Nov 3, Dec 2. June, July, August reach very high or extreme levels — apply SPF 50+, wear a hat and protective clothing, and limit direct sun between 11:00 and 17:00.
What is the UV index in Cádiz in July?
July is the peak UV month in Cádiz, with a daily-peak UV index of 9 (very high). At this level, sunburn can occur in under 20 minutes on unprotected fair skin. Apply SPF 50+, wear protective clothing and a hat, and avoid direct midday sun (11:00–17:00).
How high can UV get in Cádiz 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 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: March, April, May, October, November. Plan sun protection for the worst case, not the average.
Is air quality in Cádiz bad for travelers?
PM2.5 (fine-particle pollution) exceeds the WHO sensitive-group guideline (15 µg/m³) in 2 months: August, December. The worst month is August with a typical-day mean of 10 µg/m³ (moderate); on the worst 10% of days PM2.5 reaches 16 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.
