When it comes to iconic Southern California summer traditions, few events rival Opening Day at the Del Mar Racetrack. Equal parts sporting event, fashion show, social gathering, and coastal celebration, Opening Day marks the official start of the Del Mar Thoroughbred Club’s summer racing season and attracts thousands of visitors from across California and beyond.
Known for its glamorous hats, oceanfront setting, celebrity sightings, and electric atmosphere, Opening Day has become one of San Diego’s most anticipated annual events. Whether you’re attending for the first time or making it an annual tradition, this guide covers everything you need to know—from what to wear and when to arrive to where to stay for the ultimate Del Mar experience.
What Is Opening Day at Del Mar?
Opening Day is the kickoff event for the Del Mar Thoroughbred Club’s summer racing season. Since the racetrack opened in 1937, the event has evolved into one of the most celebrated social occasions in Southern California. Del Mar’s famous slogan, “Where the Turf Meets the Surf,” perfectly captures the venue’s unique combination of world-class horse racing and coastal California charm.
The event is about far more than horse racing. Opening Day has become known for:
- Elegant fashion and statement hats
- The legendary Hats Contest
- Trackside parties and entertainment
- Premium dining experiences
- Celebrity and influencer appearances
- High-energy betting and racing action
- A festive summer atmosphere unlike anywhere else in California
Each year, thousands of race fans, fashion enthusiasts, and visitors descend on Del Mar to celebrate the start of racing season. Opening Day remains one of the racetrack’s largest and most anticipated events.
Why Opening Day Is Such a Big Deal
Unlike many sporting events, Opening Day blends luxury, entertainment, and tradition.
For locals, it signals the unofficial start of summer in North County San Diego. For visitors, it’s an opportunity to experience one of Southern California’s most iconic events while enjoying the beaches, restaurants, and coastal lifestyle that make Del Mar so desirable.
The atmosphere is often compared to a West Coast version of the Kentucky Derby. Guests arrive dressed in colorful dresses, tailored suits, fascinators, and extravagant hats, creating a scene that’s as memorable as the races themselves.
The Famous Opening Day Hats Contest
No discussion of Opening Day is complete without mentioning the Hats Contest.
One of Del Mar’s most beloved traditions, the contest encourages guests to showcase creative, elegant, and eye-catching headwear. Categories typically include:
- Most Glamorous
- Best Fascinator
- Best Flowers
- Best Racing Theme
Thousands of dollars in prizes are awarded annually, and participation has become a signature part of the Opening Day experience.
Even if you’re not entering the competition, dressing up is part of the fun. You’ll see everything from sophisticated wide-brimmed hats to elaborate custom fascinators that rival those seen at major international racing events.

Popular choices include:
- Floral dresses
- Bright summer colors
- Elegant jumpsuits
- Fascinators

Traffic around Del Mar, Solana Beach, and Via de la Valle can become extremely congested on Opening Day, so allowing extra travel time is essential.

Special events often include:

- VIP hospitality areas

The popular Opening Day Party has become a destination in itself, attracting visitors who may never place a bet but want to experience the excitement and energy of the event.
