Paddleboarding Basics: What You’ll Need

Getting started is easier than you might think, especially if you’re just planning a quick trip. Here’s a basic gear checklist to keep things fun and safe:

  • Paddleboard – Beginners tend to do better with wider, more stable boards. You can rent one before you commit to buying.

  • Paddle – Adjustable paddles work best and should match your height.

  • Life jacket (PFD) – Safety first! It’s required in most places and smart to wear no matter your skill level.

  • Leash – This attaches you to your board so you’re not stranded if you fall off.

  • Clothing – Quick-dry clothes or swimwear work well. If it’s chilly, go for a wetsuit or layers.

  • Sun protection – Sunglasses, sunscreen, a hat—anything to keep you protected while you’re out there.

Stay Safe and Have Fun: Quick Tips for the Water

Paddleboarding is low-risk, but a few simple precautions go a long way. Here’s what to keep in mind before you head out:

  • Check the weather. Sudden winds or storms can turn an easy paddle into a tough situation.

  • Know the area. Each water body is a little different. Take a minute to get familiar with the layout, currents, or any rules.

  • Bring snacks and water. Paddleboarding can be more tiring than it looks!

  • Go with a buddy. It’s always more fun (and safer) with someone else.

  • Tell someone your plan. Especially if you're heading out solo.
