When to Visit Cadiz

January in Cadiz is cool and occasionally rainy, with highs of 16°C (60°F) and lows around 9°C (49°F). Rainfall averages around 58mm for the month, arriving mainly in passing fronts rather than constant drizzle. Crowds are low. It feels like a Spanish city in its everyday rhythm, café tables still occupied on sunny afternoons, the cathedral and the old town unhurried.

February remains cool, with highs of 16°C (60°F) and lows of 10°C (50°F), and rainfall eases slightly to around 51mm. This is Carnaval month, and for roughly ten days the city transforms in a way that is hard to describe without witnessing it, satirical song groups, elaborate costumes, and a collective atmosphere that spreads well beyond the official events. Crowds are medium during Carnaval, low otherwise.

March starts to feel like the turn toward spring, with highs climbing to 18°C (65°F) and lows around 12°C (54°F). Rainfall stays relatively high at around 56mm. But the wet spells tend to alternate with long stretches of clear Atlantic light. Crowds remain low, which makes March a quietly good time for exploring Cadiz at leisure.

April is when the city properly opens up, with highs of 20°C (68°F) and lows of 14°C (57°F). Rainfall drops to around 43mm and sunshine becomes the dominant expectation rather than the exception. Crowds build to medium levels as Semana Santa (Holy Week, dates vary) draws visitors from across Spain. The warmth is enough for café terraces and long evening walks along the seafront.

May settles into reliably pleasant territory, highs of 23°C (73°F), lows of 16°C (62°F), and rainfall down to around 30mm. The sea hasn't yet warmed to comfortable swimming temperatures for most visitors. But the beach promenades and the old town fill up pleasantly. Crowds are medium and rising toward the summer peak.

June flips the switch to dry. Rainfall shrinks to 5mm for the entire month and highs hit 25°C (77°F). Nights hover at 19°C (67°F), so you can linger outside without grabbing a jacket. Beaches fill fast, bars stay open later, and the Atlantic breeze keeps everything honest. Crowds move to high.

July owns the summer crown in Cadiz. Expect 27°C (81°F) by day, 21°C (70°F) after dark, and months that log 0mm of rain. The levante wind can trick you into feeling hotter. Yet most hours are textbook beach weather. Beds sell out early. Evenings glow, light ricocheting off the sea and the white facades of the old city. This is the Cadiz that ends up framed on walls.

August turns the thermostat to max. Highs reach 28°C (82°F), lows settle at 22°C (72°F), and rainfall stays at 3mm, basically a rounding error. Spanish holiday-makers and international visitors pile in together. Sand pulses with life, tables are scarce, and the whole city feels like a long toast. Finding silence demands effort. Crowds are at their highest.

September eases its grip. Highs slip to 26°C (78°F), lows to 20°C (68°F), and rainfall climbs to 28mm, arriving in quick, dramatic bursts. The sea, warmed all summer, is at its best. Crowds fall from August's summit to medium-high. The city exhales. Worth serious consideration.

October signals a sharper shift. Highs drop to 23°C (74°F), lows to 17°C (63°F), and rainfall jumps to 76mm. Wet spells can linger. Yet clear days still outnumber gloom. Tourists thin out fast. What remains is Cadiz for locals, animated and unfiltered. Crowds drop to medium-low.

November brings the wettest skies. Rainfall totals 86mm, highs sit at 19°C (67°F), and lows dip to 13°C (56°F). Atlantic fronts roll through on schedule. Grey stretches are real. Still, baroque facades shine under flat light, and tapas bars hum with neighborhood voices. Crowds are low.

December wraps the year quietly. Highs reach 17°C (62°F), lows settle at 11°C (51°F), and rainfall holds at 76mm. Christmas lights add modest sparkle. Yet the rhythm stays calm. Locals call it cold. Visitors from northern Europe or North America often smirk and unzip. Crowds are low.
