Romantic and Dreamy
The princess look for a fairy tale wedding is a great look and goes with the theme too. A simple coif with sweeping sensual curls just cannot go wrong. Wear a diamond or a floral tiara with it, as you are ready to go. Another dreamy look, is a loosely tied bun, with curls floating down on your shoulders. Wear a tropical flower behind your left ear. Beach wedding hairstyles with flowers accentuates the feminine side in a very poetic way.
Timeless and Classic
Classic hairstyles for weddings can never go wrong. No matter what the texture of your hair is and what the theme of your wedding is, these hairstyles are simply timeless. You can try the beach wedding hairstyles for long hair for this look. Since you have long hair, the chances of them getting tangled because of the wind are higher. I suggest, straighten them, this way they wont give you much trouble. A chignon, which will show off your nape is the best way of getting the sophisticated look for your dream wedding.

Modern and Minimalistic
Modern hairstyles are slightly unconventional. For instance short hairstyles with bangs, is not something you'd see in a wedding. You can have you hair cut short or have them long for these sassy hairstyles, the choice is yours. A tightly pulled ponytail at the back or a plain bob is all it takes to make a bold fashion statement at your wedding. Wear a satin hairband, keep the long locks flowing down your back and walk down the aisle with confidence to make the day memorable.
Earthy and Casual
For the wild child look, just don't do anything with your hair. If they have a wavy structure don't try to tame them otherwise. For an earthy feel, wear a tiara of olive leaves and small white flowers. Lightly place the white tulle veil and wear the majestic look as you begin your new life. I suggest to get this look just as you've dreamed of it, grow your hair long or wear extensions.
Breezy and Beach
This one is my favorite. For a relaxed breezy look, pin up your hair, with a pin that's made of seashells or a star fish. You don't have to spend hours and hours on fixing this hairstyle. All you need to do is pin up a few strands and leave the rest. Keep it as casual as possible. This will give you an innocent look.
So, these were some of the casual beach wedding hairstyles. You can also go for a formal look if the wedding theme demands so. Since you are having a beach wedding, wear minimal make up. The nude simple look will look beautiful against the serenity of the surroundings. Good luck!
