If you’re planning a trip to the land of sherry and dancing horses, you’ve probably checked the forecast and thought, "Oh, it's southern Spain, it’ll be hot." Well, yes. But also, no. Honestly, the weather in Jerez Spain is a bit of a moody character that doesn't always play by the rules of a standard Mediterranean postcard.
Jerez de la Frontera sits in a weird geographical pocket. It’s only about 12 miles from the Atlantic, but it feels significantly more "inland" than its neighbor, Cádiz. This small gap makes a massive difference. You get the brutal heat of the Guadalquivir valley, but every now and then, the ocean decides to remind you it’s there with a damp, salty breeze.
The Winds That Literally Change Your Mood
You can't talk about the climate here without mentioning the winds. They aren't just weather events; they are cultural phenomena. Locals talk about the Levante and the Poniente like they're unruly relatives who just showed up for dinner.
The Levante is the one people fear. It blows in from the east, from the Mediterranean, and by the time it hits Jerez, it’s dry, hot, and relentless. It can last for days—three, seven, sometimes nine. It’s a "hairdryer" wind. People get irritable. There’s even an old (and legally dubious) myth that you could get a lighter sentence for a crime committed while the Levante was blowing because it "drives people mad."
Then there’s the Poniente. This is the "good" wind. It comes from the west, off the Atlantic. It’s cool. It’s humid. In the summer, when the thermometer is screaming at 40°C, a shift to the Poniente feels like someone finally turned on the air conditioning. It brings that vital "rocío" (dew) that keeps the Palomino grapes from shriveling up in the vineyards.

Summer is a Different Beast
Let’s be real: July and August in Jerez are intense. If you aren't a fan of sweating while standing still, these months might test your patience. We aren't just talking "warm." We're talking "don't touch the steering wheel of your car or you'll lose a layer of skin" hot.
Average highs sit around 34°C (93°F), but that’s a deceptive average. In 2024 and 2025, we saw spikes hitting 42°C (108°F) with alarming regularity. The city basically shuts down between 2:00 PM and 7:00 PM. This isn't laziness; it's survival.
- The Siesta is mandatory. Do not try to go sightseeing at 3:00 PM. The Alcázar will be empty, but you will also be a puddle.
- Nightlife starts late. Dinner at 10:00 PM feels early when the stones of the buildings are still radiating heat from the afternoon sun.
- Humidity matters. Unlike Seville, which is bone-dry, Jerez gets some Atlantic moisture. This makes the heat feel "heavier" on some days, though it helps the vineyards survive.
When it Actually Rains (and it Really Does)
People think Andalusia is a desert. It’s not. In fact, the nearby Sierra de Grazalema is one of the wettest spots in all of Spain. Jerez gets its fair share too, mostly concentrated between November and February.
When the weather in Jerez Spain turns wet, it doesn't usually drizzle. It pours. You’ll get these "Atlantic fronts" that dump a month's worth of rain in two days. The streets—many of which are old and weren't exactly designed for modern drainage—can turn into small streams pretty quickly.

November is statistically the wettest month, averaging about 100mm of rain. If you're visiting then, bring a real umbrella, not a flimsy travel one. The wind will snap it in seconds.
The Secret "Best" Times to Visit
If you want the "Goldilocks" weather—not too hot, not too cold—you have two specific windows.
Late April to Early June: This is peak Jerez. The orange blossoms have finished, but the jasmine is starting. The Feria del Caballo (Horse Fair) usually happens in May. The daytime temps are a gorgeous 24°C to 28°C. You can walk around all day without needing a gallon of water, and the evenings are crisp enough for a light jacket.
September and October: The "Sherry Festival" (Fiestas de la Vendimia) happens in September. The harvest is in, the air is starting to lose that jagged summer edge, and the light is incredible. It’s a golden, soft light that photographers go crazy for.

Winter: Mild but Sneaky
Winter in Jerez is "cold" for locals, which means it’s about 15°C (59°F) during the day. For anyone coming from London, Berlin, or New York, it feels like a nice spring day.
But here’s the catch: Spanish houses are built to keep heat out. They are made of stone and tile. When the sun goes down and the temperature drops to 5°C (41°F), the inside of a traditional Jerezano house can feel like a refrigerator. If you're booking an Airbnb for January, check if it has heating. Many don't, or they rely on small electric radiators that struggle against the damp winter air.
A Quick Breakdown of What to Expect:
January & February: Cool and damp. Highs of 16°C, lows of 5°C. Great for visiting bodegas (the thick walls keep it surprisingly comfortable).
March & April: Unpredictable. You might get a week of pure sun or a week of solid rain. This is the "Semana Santa" gamble.
May & June: Perfection. Long days, blue skies, and everything is green before the summer sun toasts it brown.
July & August: The furnace. Only for those who love the heat or plan to spend 1:00 PM to 7:00 PM in a swimming pool.
September & October: The second spring. Warm days, cooler nights, and perfect for wine tasting outdoors.
November & December: The rainy season starts. Quiet streets, cozy "zambombas" (flamenco Christmas parties), and short days.
Actionable Tips for Navigating the Climate
- Hydrate differently. Don't just drink water. The locals drink rebujito (sherry mixed with lemonade and mint) during festivals for a reason—it’s refreshing—but stick to mineral water with a squeeze of lemon to stay hydrated in the August heat.
- Dress in layers for Spring/Fall. The temp can swing 15 degrees between 3:00 PM and 9:00 PM. A linen shirt is your best friend here.
- Follow the shadows. You'll notice locals walking on one side of the street and then crossing over. They are following the "sombra" (shade). Join them. It’s usually about 5 degrees cooler under an awning.
- Check the wind forecast. Apps like Windguru or Windy are more useful than standard weather apps in Jerez. If it says Levante is coming, plan indoor activities like a museum or a deep-cellar bodega tour.
The weather in Jerez Spain isn't just a backdrop; it dictates the pace of life. Respect the sun, embrace the siesta, and always have a backup plan for a rainy Tuesday in November.
To make the most of your trip, I recommend booking your bodega tours for midday during the summer months to take advantage of their naturally cool microclimates. Also, if you're visiting in May, keep an eye on the official Horse Fair dates as they change slightly every year based on the lunar calendar and Easter.
