Wind, Weather and Water: How to Know If It's Safe to Paddle

Kayaks don't mind rain. They mind wind. Almost every beginner rescue starts the same way: a calm morning, a building afternoon breeze, and a paddler who didn't know the numbers. Learn the numbers, and deciding whether it's safe to kayak today gets easy.

Check the wind before you check the weather.

Wind Is the Thing That Ruins Days

• Fifteen knots is a pleasant day for a walk and too much for a beginner paddle. Wind builds chop, steals steering, and turns the trip home into a gym session.

• Offshore wind is the dangerous one: it blows from land to sea, flattening the water near shore so it LOOKS perfect - while pushing you away from land faster than you can paddle back. Glassy water plus wind at your back leaving shore = the trap.

• Wind against tide stacks the water into short steep chop - why the same spot is friendly at 9 am and hostile at 3 pm.

Checking the Forecast Before You Leave

• The Bureau of Meteorology is the source - it's Paddle Australia's recognised forecast source, and ours. Check the coastal waters or local forecast for wind speed and direction, and the radar. Our Kayaking Planning Checklist on our Resources page walks you through it.

Under 10 knots

Go.

10-15 knots

Sheltered water only, short trip, experienced company.

Over 15 knots

Today is a cafe day.

• Check wind direction against your location: a 12-knot onshore breeze is annoying; the same wind offshore is a hazard.

• Tides matter near the coast: plan around the change, and treat river mouths and inlets on a running tide as no-go. More on where to go kayaking.

Reading What's in Front of You When You Arrive

• Whitecaps start appearing at around 7-10 knots and become frequent at 11-16 knots. If whitecaps are spreading across the water, it's already past beginner conditions.

• Flags, trees and moored boats are wind gauges: moored boats swing to point into the wind (or the current); streaming flags mean stay ashore.

• Watch the water for five minutes before unloading - conditions reveal themselves to anyone who looks.

When Conditions Change on the Water

• Getting off the water early is the experienced move, never the failure. The wind that's building will keep building.

• Head for the nearest safe shore, not the carpark - walk back, arrange a pickup, laugh about it. The boat can be fetched; conditions don't negotiate.

• Storms and lightning: off the water immediately, non-negotiable. You are the tallest thing on a flat conductor.

When to Postpone

• The forecast test: if you're checking hourly hoping it improves, it already told you the answer.

• Paddling's great mercy - the water is still there tomorrow.
