Traveller notes on Cádiz in May
Regulars point out that weather sites showing 20-21C for this month can undersell it, since those figures are shade temperatures and a beach day in direct sun feels genuinely warmer than the number suggests. Our row backs that mild, still-dry read, 23.6C over 17.4C nights, with rain minimal at 29.6mm across 2.4 days and humidity at 62 percent. Regulars are consistent that being blown out at the beach by wind is genuinely rare here even by month's end, a real reassurance for anyone worried about the Atlantic-facing coast. The sea sits at a cool 19.4C, a little chilly for some but swimmable for many by this point. The record: 12.6 hours of sun, a 19.3 kph wind and AQI 51.
Other months in Cádiz
Regulars describe a genuine turning point partway through the month: crowds that pack the city through the first week thin out noticeably from the second week onward, with warm, sunny days and swimmable seas continuing well past that shift. Our row backs the warm, dry read, 26.8C reading as 28C over 20.9C nights, with rain almost entirely absent, 9.7mm across 1.5 days. Regulars addressing the region's notorious wind note this city sits far enough northwest of windy Tarifa to usually escape the worst of it, though when it does blow through it can persist for a few days at a time. The sea stays warm at 21.8C. The record: humidity 64 percent, 11.2 hours of sun, a 16.9 kph wind and AQI 46.
Cadiz-forum threads on October weather call it one of the better months of the year, still warm and sunny especially in the first half, with posters noting the port city itself runs a good five to ten degrees cooler than inland Andalusian towns like Jerez thanks to the sea breeze. One specific regular pins the seasonal turn precisely: rain typically doesn't arrive until around October 23rd, meaning the first three weeks of the month are usually reliably dry and good for sightseeing or the beach. Early-to-mid October is consistently rated the sweet spot, comfortable temperatures without July and August's more intense heat, while still warm enough for a swim on a good day. The back end of the month becomes more of a genuine toss-up once that rain window opens up. The record: 24.3C days feeling like 24C, 18.5C nights, 67mm across 5.3 days, a 21.3C sea, 68 percent humidity and 9.4 hours of sun.
June on the Costa de la Luz is beach weather before the July and August crowds - regulars give about 30C by day falling to around 15C in the early morning, against our row's 26C and 20.2C, with 0.7 precipitation days. The variable that decides the day is the levante, the easterly that funnels through the Strait and can blow hard all the way to Gibraltar. It is genuinely unpredictable, and the forum's answer is geographic rather than seasonal: if it is up, head for Canos de Meca or Bolonia, which are more sheltered than the exposed Atlantic strands. Our row carries 19 kph as the monthly mean. The record: 6.2mm of rain, humidity 59 percent, 13.1 hours of sun and a 21.8C sea.
August in Cadiz is mid-30s C by day, low-to-mid 20s in the evening, and full of Spaniards who have come to the coast for exactly that reason - beaches crowded, traffic slow, parking a project. The local variable is the Levante, the wind that funnels out of the Mediterranean through the Straits into the Atlantic. Regulars call it brutal when it blows and are practical about it: the southwest-facing Calas de Roche sit in six little coves with the wind passing overhead, and La Barrosa is eight kilometres long, so there is room even in August. One poster's consolation - when the Levante was up, they had a beach to themselves. The record: 28.8C days, 22.7C nights, 0.6 precipitation days, 12.5 hours of sun and a 22.3C Atlantic.
