Watermelon Smoothies Are Back at Smoothie King for Summer 2026

Our delicious watermelon smoothies are back for a limited time this Summer 2026, and we've brought back our fan-favorite watermelon blends specifically to help you cool down and stay hydrated with the kind of refreshment that genuinely tastes like summer in every sip.

If you've been waiting all year for that first refreshing taste of cold, fresh watermelon blended into a smoothie, we're happy to tell you the wait is officially over. Our seasonal watermelon lineup is built entirely around real fruit, zero artificial flavors, and the kind of deep, lasting hydration your body actually needs when the temperature starts to climb.

We don't approach summer halfway, and we don't think you should either. Which is exactly why we made sure this lineup was worth the wait.

Why We Brought Watermelon Smoothies Back for Summer 2026

Our guests made it clear that watermelon is one of the most beloved seasonal flavors we've ever offered, and after hearing that enthusiasm year after year, Summer 2026 felt like exactly the right moment to give this fan-favorite the spotlight it deserves.

Watermelon is roughly 92% water, making it one of nature's most naturally hydrating fruits available. Pairing that with our Clean Blends Promise of no high fructose corn syrup, no artificial colors, no GMO fruits or vegetables, gives you a smoothie that does far more than simply taste good on a hot afternoon. Our delicious watermelon smoothies are available as a limited-time offering, meaning once summer winds down, they'll be off the menu until next season arrives, so we genuinely encourage you to take advantage while they're here.

What's in Our Watermelon Smoothies?

Every blend on our menu is built with a clear purpose in mind, and our watermelon smoothies are absolutely no exception to that standard. Here's a closer look at what makes them work so well as a seasonal offering:

• Real watermelon juice: We use real fruit juice in every blend, never artificial flavoring or syrup substitutes

• Clean Blends Promise: Every smoothie we make excludes artificial colors, flavors, preservatives, and hydrogenated oils entirely

• Customizable enhancers: We offer protein, energy, or immune support add-ons so you can align each smoothie with your specific wellness goal

• 0g added sugar options: Many of the watermelon blends are available with zero grams of added sugar

Our Clean Blends Promise required more than five years and over 15,000 hours of dedicated research and development to perfect, and during that process, we reformulated more than 150 individual ingredients to eliminate anything we wouldn't feel confident serving to our own families. And that same exacting standard applies to every watermelon smoothie we blend this summer.

Pair It With a Power Eats™ Item

Watermelon brings more hydration to your routine, while protein brings the sustained satisfaction that keeps you going through your busiest summer days, and together they create what we consider a genuinely complete summer meal worth looking forward to. We encourage you to try any of our delicious watermelon blends alongside one of our new Power Eats™ food menu items, such as a Loaded Avocado Toast with 11 grams of protein or a Loaded Peanut Butter Toast with 15 grams of protein.

Hydrate Your Soccer Summer

Summer soccer season starts soon, and whether you are on the pitch or cheering from the stands, staying hydrated is non-negotiable.

Soccer demands everything from your body. Ninety minutes of sprinting, cutting, and competing at full intensity means your hydration strategy matters as much as your training. That is exactly why Watermelon Hydration was built the way it was. Packed with electrolytes and zero grams of added sugar, it replenishes what competition takes out without the crash that comes from sugar-loaded drinks.

This summer, as the world tunes in to the greatest sporting event on the planet, make Smoothie King your go-to stop before the game, at halftime, and after the final whistle. The delicious watermelon lineup was made for a summer like this one.

Why Choose Smoothie King

We've been blending purpose-driven smoothies since 1973, when our founder Steve Kuhnau first began crafting them to actively improve his own health outcomes, and that founding story continues to inform every decision we make about what goes into our menu. Every blend we serve is built specifically around your goal, whether that goal is fitness performance, weight management, general wellness, sustained energy, or simply enjoying a satisfying treat you can feel good about.

What genuinely sets us apart from other options is our absolute refusal to cut corners when it comes to ingredients, which is why our No-No List formally excludes artificial flavors, high fructose corn syrup, hydrogenated oils, GMO produce, trans fats, gluten, and any NSF-banned substance from every product we offer. When you order from us, you're not getting a sugar-loaded drink with hidden ingredients. You're getting a smoothie with a purpose, backed by decades of expertise and a genuine commitment to your wellbeing.

FAQs

How long will watermelon smoothies be available?

Our delicious watermelon smoothies are a limited-time offering available throughout Summer 2026 while supplies last. We don't publish a specific end date because availability can vary by location and overall seasonal demand. Our experience with past limited-time blends tells us these offerings tend to sell out before the official end of summer arrives. We recommend ordering through our app or visiting your nearest location soon to make sure you don't miss out on the season's most refreshing blend.

Can I customize my watermelon smoothie?

Yes, you can add nutritional enhancers, including whey or plant-based protein, energy boosters, immune support, or additional fiber to any watermelon blend we offer. You can also adjust your serving size, swap the base ingredient, or pair your smoothie with one of our Power Eats™ food menu items to build a more complete and satisfying summer meal.

Do watermelon smoothies have added sugar?

Many of our watermelon smoothies contain 0g of added sugar, with all of their natural sweetness coming directly from real fruit rather than added sweeteners, which works particularly well with watermelon since the fruit is already naturally sweet on its own. We always encourage you to review the detailed nutritional information available in our app for whichever specific blend and customizations you select, so you can make the most informed choice for your goals.

Where can I order a watermelon smoothie?

You can order any of our watermelon smoothies at any of our locations across the country or conveniently through the Smoothie King app for pickup or delivery, and our website's store locator will help you find the nearest location quickly. If you're a Healthy Rewards member, you'll earn points on every order you place, so we'd encourage you to sign up before your next visit if you haven't already done so.
