Why Temecula Valley’s Climate is Perfect for Wine Grapes… And Vacationers!

“It’s too hot to grow wine grapes in Southern California.”

We hear this a lot out in Temecula Valley. Every time we do, we smile to ourselves as it’s an open invitation to explain why this wine region is not only perfect for vacationers, but for producing world-class wines as well.

Picture your ideal vacation. Does the image of waking up to a beautiful sunrise that warms the air just enough that you can enjoy coffee out on your balcony or get in a quick morning run in slightly crisp air with no sticky humidity sound about right?

Does sitting on a patio enjoying a Southern California lunch in 72-degree weather, sun shining, not a cloud in the sky in mid-November while your friends back home are kicking muddy slush from an early snowfall off their boots before getting into their cars on a grey and dreary day sound appealing?

Imagine yourself in a luxurious king-sized bed at your hotel after a fun and sun-filled day of wine tasting, hiking or shopping, all windows open to allow in the cool night breezes to lull you to sleep.

This is vacationing in Temecula Valley, all year round. It also describes key aspects that make this region suitable for growing wine grapes.

A Mediterranean Climate is generally classified as having a long growing season (early Spring to late Fall) of moderate to warm temperatures, moderate winters and relatively low rainfall. Since regions of Mediterranean climate are influenced by cold ocean currents during the Summer months, the weather during this time is dry, stable and pleasant with strong diurnal shifts. This means that, while the days are warm and sunny, the nights cool down quickly. These regions receive most of their precipitation for the year during the Winter months.

Major wine producing regions with Mediterranean climates include Tuscany and parts of Southern Italy, the Southern Rhone Valley, Provence, most of Greece, many parts of Spain, Southern Oregon, Baja California, the Napa Valley and, of course, Temecula Valley. These are many of the regions we think of when we think of premium wines and dream travel experiences.

What makes Temecula Valley at home among these well-known wine regions is that it boasts long, sunny days that allow wine grapes to ripen and develop the sugars that will ultimately turn the grapes into wine. However, the region is home to significant maritime influence as well. Just 22-miles from the Pacific Ocean, Temecula Valley is bordered by coastal mountain ranges and inland valleys. As the sun warms the inland valleys east of Temecula, the warm air rises, forming a low-pressure area which pulls the cooler, much heavier air from the Pacific Ocean in through two breaks in the mountains — The Rainbow Gap and the Santa Margarita Gap. This cool air creates the pattern of warm sunny days, breezy afternoons and cool nights, ideal conditions for the wine grapes to develop complex flavors and aromas, while retaining pleasant balance and freshness from desirable acidity levels.

Think about it: Virtually year-round sunshine and warm or moderate temperatures, cool nights, relatively little rainfall, not to mention high quality wines, unique wine-tasting experiences, and the relaxed, welcoming vibe that is synonymous with Southern California. Whether you’re a wine enthusiast or just looking for a dream vacation, Temecula Valley should be added to your list of top wine destinations to visit.
