National Watermelon Day lands on August 3, 2026 — peak season for the fruit and peak temperatures across Mountain View. Plenty of food blogs will tell you exactly where to find a watermelon agua fresca today. We’d rather give you a straight answer: our current menu doesn’t list a flavor-specific watermelon drink, so we’re not going to pretend it does.
What We Can Actually Confirm
Los Altos Taqueria’s menu includes a real agua fresca program, sized rather than flavored on the current price list: Agua Chica at $3.12 and Agua Grande at $4.16. There’s also Fresh Juice, available in a 20 oz size for $8.32 or a 32 oz size for $11.44. Aguas frescas are traditionally rotated by whatever fruit is freshest that day — watermelon (sandía), horchata, and jamaica (hibiscus) are all common flavors in Jalisco-style kitchens — but our menu data doesn’t itemize which flavor is running on any given day. If you’re hoping for sandía specifically, the honest move is to call ahead or ask at the counter when you arrive.
Other Genuinely Cold Options on the Menu
If watermelon isn’t the flavor of the day, Los Altos Taqueria’s menu has other confirmed cold options built for a 90-degree afternoon. A Michelada ($11.44) is a classic Mexican beer cocktail served ice-cold, and Imported Beers ($6.24) or a Margarita ($11.44) are straightforward warm-weather choices for anyone 21 and up. For a non-alcoholic option beyond the aguas frescas, a Domestic Soft Drink ($2.08) or Imported Drink ($4.16) will do the job in a pinch.
Why We’re Not Inventing a Watermelon Special
It would be easy to slap “Sandía Day Special” on a graphic and call it content. We’re choosing not to, because our menu data is the one thing on this page we won’t guess at. What we can say honestly: our agua fresca and fresh juice program is real, it rotates by what’s fresh, and watermelon is a completely plausible flavor to find in it on any given day in August — just not one we can promise from the menu sheet alone.
How to Order
Aguas frescas, fresh juice, and every other beverage on the list are available to order directly, every day the restaurant is open — 7:00 AM to 10:00 PM, Monday through Sunday. Order ahead online for pickup, or call to ask what flavor is pouring today before you make the trip.
