Australia is blessed with some of the world's most beautiful beaches, and whether you're a dedicated surfer catching dawn waves or a casual beachgoer enjoying a summer weekend, the right pair of board shorts makes all the difference. Originally designed for surfers who needed shorts that could handle the demands of riding waves, board shorts have evolved into versatile beach wear that balances performance with style.

Having spent countless hours in the water at beaches from Bondi to Margaret River, I've learned what separates great board shorts from merely adequate ones. This guide shares that knowledge to help you choose board shorts that will serve you well in Australian conditions.

What Makes Board Shorts Different

Board shorts are specifically engineered for water activities. Unlike regular shorts or swim briefs, they're designed to stay comfortable whether wet or dry, withstand the abrasive effects of sand and salt water, and move with you during active water sports.

The key differences from other shorts include quick-drying synthetic fabrics, longer lengths that provide coverage while sitting on a surfboard, four-way stretch for unrestricted movement, and construction details like flat seams and no exposed hardware that could scratch a board or cause discomfort.

Choosing the Right Length

Board shorts length has evolved significantly over the decades, from the short shorts of the 1960s to the below-the-knee styles of the early 2000s, and back toward more moderate lengths today. Finding the right length for you depends on your activities and personal preference.

Short Length (16-18 inches)

Shorter board shorts offer better freedom of movement and are popular among serious surfers and those who want a more athletic look. They sit above the knee and don't bunch up when you're paddling or popping up on your board. However, they provide less coverage and sun protection for your thighs.

Medium Length (19-20 inches)

This is the sweet spot for most people. Medium-length board shorts sit around the knee, providing good coverage while still allowing free movement. They're versatile enough for surfing, swimming, and transitioning to casual beach wear without looking overdressed or underdressed.

Long Length (21-22 inches)

Longer board shorts extend past the knee and offer maximum coverage and sun protection. While they can feel slightly restrictive for serious surfing, they're popular for casual beach days and among those who prefer more modest coverage. Just be aware that very long board shorts can look dated.

Length Selection Tip

When trying on board shorts, sit down as if you're straddling a surfboard. The shorts should rest comfortably without bunching up excessively. For surfing, err toward shorter lengths. For general beach use, mid-lengths offer the best versatility.

Understanding Board Shorts Fabrics

The fabric of your board shorts determines how quickly they dry, how comfortable they feel, and how long they'll last. Modern board shorts use advanced synthetic materials designed specifically for water activities.

Polyester

The most common board shorts material, polyester is durable, quick-drying, and resistant to chlorine, salt water, and UV damage. Higher-quality polyester feels softer and more comfortable against the skin. Look for recycled polyester options if environmental impact is a concern.

Nylon

Lighter and softer than polyester, nylon dries even faster and has a silkier feel. However, it's slightly less durable and more susceptible to UV degradation over time. Nylon board shorts are particularly popular for their comfort.

Stretch Blends

Most quality board shorts incorporate elastane or spandex (typically 2-5%) for four-way stretch. This allows the shorts to move with your body during dynamic activities without restricting your range of motion. Stretch is particularly important if you're surfing, bodysurfing, or engaging in active beach sports.

Fabric Features to Look For
  • Quick-dry technology for comfort in and out of water
  • Four-way stretch for unrestricted movement
  • UPF rating for sun protection (UPF 50+ is ideal)
  • Salt water and chlorine resistance for durability
  • Lightweight construction that won't weigh you down when wet

Essential Features for Quality Board Shorts

Beyond fabric and length, several construction details separate quality board shorts from cheap alternatives.

Closure System

Traditional board shorts use a velcro fly with a lace-up or neo-fly closure. This combination provides security without the risk of metal hardware scratching your surfboard. Some modern designs use hidden snap closures or stretchy waistbands. Whatever the system, ensure it feels secure even during active movement.

Waistband Design

A well-designed waistband sits comfortably on your hips without digging in or sliding down. Some board shorts feature elastic sections or drawstrings for adjustability. Consider how the waistband will feel when you're lying on a surfboard paddling out.

Pocket Placement

Pockets on board shorts should have secure closures to prevent losing valuables in the surf. Velcro, zippers, or drain mesh are common. Side pockets are convenient for casual use, while back pockets with key loops offer secure storage. Avoid shorts with bulky pockets that create drag in the water.

Seam Construction

Quality board shorts use flat-lock or blind-stitched seams that lie flat against your skin, preventing chafing during extended use. Raised or rough seams can cause irritation, especially when combined with sand and salt water.

About Drain Holes

Some board shorts feature small drain holes in the pockets or mesh sections that allow water to escape more quickly. While useful, they're not essential if the overall fabric has good quick-dry properties. Don't put too much weight on this feature when comparing options.

Board Shorts for Australian Conditions

Australia's intense sun and unique beach conditions warrant some specific considerations when choosing board shorts.

Sun Protection

Australian UV levels are among the highest in the world. Board shorts with UPF ratings provide measurable sun protection for covered skin. While you'll still need sunscreen on exposed areas, UPF-rated shorts help reduce your overall UV exposure. Dark colours generally offer better UV protection than light colours.

Handling the Surf

Australian beaches often feature powerful waves and strong currents. Board shorts designed for surfing should stay securely in place even during wipeouts and tumbles. Test the fit by moving actively when trying shorts on, and ensure the waistband closure feels bomb-proof.

Sand Resistance

Fine Australian beach sand has a way of getting everywhere. Smoother fabric surfaces shed sand more easily than textured ones. Also consider that dark colours hide wet sand marks better than light colours, though they absorb more heat in the sun.

From Beach to Street

One of the great things about modern board shorts is their versatility. A well-chosen pair transitions seamlessly from the beach to lunch at a beachside cafe or a casual walk through town.

For maximum versatility, choose board shorts in solid colours or subtle patterns rather than loud graphic prints. A cleaner aesthetic works in more settings. Medium lengths (around 19-20 inches) also look appropriate in more contexts than very short or very long options.

Consider having at least two pairs: one for serious water activities where performance is paramount, and another more stylish pair for casual beach days where looks matter more than pure functionality.

Caring for Your Board Shorts

Proper care extends the life of your board shorts significantly. Rinse them with fresh water after every use to remove salt, sand, and chlorine, which can all degrade the fabric over time. Wash with mild detergent in cold water and air dry away from direct sunlight.

Avoid leaving wet board shorts bundled up in your bag or car, as this promotes mildew and odour. Most quality board shorts dry quickly enough that you can rinse and hang them immediately after use.

What to Expect at Different Price Points

Board shorts range from budget options under $30 to premium pairs exceeding $100. Here's what you generally get at each level.

  • Budget ($20-40): Basic construction, standard fabrics, limited stretch, adequate for occasional beach use
  • Mid-Range ($50-80): Quality fabrics, good stretch, better construction, comfortable for regular use, suits most people
  • Premium ($90+): Advanced fabrics, superior comfort, durable construction, designed for serious water athletes, worth it for frequent surfers

For casual beachgoers, mid-range board shorts offer excellent value. If you're surfing regularly or spending significant time in the water, investing in premium shorts pays off in comfort and durability.

Final Thoughts

The best board shorts for you depend on how you'll use them. Surfers should prioritise performance features like stretch and secure closures. Casual beachgoers can weight style and comfort more heavily. Everyone benefits from quick-dry fabrics and quality construction.

Don't underestimate the importance of proper fit. Board shorts that ride up, bunch, or slip down will frustrate you every time you wear them. Take time to try options on and move around in them before buying. The right pair of board shorts becomes a summer staple you'll reach for again and again.
