Default Cold Fronts, One Example

Kiteboarding Weather Planning And Monitoring

1. Marine/Water & Hazard Forecasts
Check reliable forecasts (predicted winds, direction, HAZARD FORECASTS, temperatures, anticipated changes, cold fronts, tropical or strong systems). Anticipate changes donít fall into them. Not all private weather sites are reliable, use what works well in your area. Will your kite size work for the day or will you need to increase or decrease size at some point. How about exposure clothing, is there a sudden temperature drop inbound?

2. Radar and Satellite Maps
Is stormy weather (often bright colored masses), squall lines, isolated storm clouds or feeder bands inbound? Looping weather images can show CURRENT trends and speed. Does it look they will arrive during your session? Temper this with LOCAL knowledge as conditions can change radically in only an hour sometimes, systems can accelerate or stall, etc..

3. Synoptic/Frontal Weather Maps
Are there significant weather systems inbound, cold fronts, tropical systems, strong high/low pressure, got tight pressure isobars for strong wind? Look at these maps on loop again to learn about CURRENT trends and speed.

4. Real time winds
How are winds upweather or the direction of the prevailing system, spikes/gusty and shifting winds inbound? Frequently you can see a preview of what the front will bring to your area, hundreds of miles upweather in advance. Itís a free look at what may be the future, why not take it? If unstable weather is coming avoid it until it passes.

5. Wind Useable or NOT?
If you decide to go, STAY AWARE, at all times of the weather. Things like cloud lines, funnel clouds, wind direction and velocity, white caps, mist, temperature changes. Typical weather patterns can be recognized within given seasons. Learn what to look for and when to react. Good chance you are a wind junkie already so play the complete roll and tune into wx. Measure wind speed at the launch along with other visual indicators such as white caps, tree and flag movement and ask how other kiters are doing on their respective kite sizes before selecting yours. If you expect a weather change to occur, don't be on the water if something violent comes through. Sometimes the hazardous period can be short so just wait it out.

6. At the beach & riding
Checkout wind speed, direction, sky and water conditions at the launch and during your session. Is the wind useable, are sky conditions stable or threatening? What do threatening sky conditions look like in your area? You should know. Are there dark clouds and/or a wind/whitewater inbound? What about funnel clouds or waterspouts, are there small points showing up at the bottom of clouds? Always be aware of your surroundings, weather changes, ANTICIPATE & REACT early.

7. Squall is almost here!
Land, thoroughly secure gear early, before significant wind, temperature changes or threatening weather arrives. Systems can move 50 mph + hitting with minimal warning. If caught on the water, consider totally or emergency depowering early, waiting too long has taken riders. Be ready to release your kite leash if your kite powers up again. Riding out far from shore may work for ships. Ships donít get ripped 50í+ from the water and blown at high speed downwind. DON'T WAIT, act early to kill the power of the kite even if it means swimming in after. Your strong swimming skills and impact vest should make that a manageable process.


Want to learn more, plug into your local situation and build up a strong weather sense and knowledge of predictive and realtime weather informational sites. Be careful about less violent gusts. Guys have been injured by gusts as little as 10 kts. above background. Going to 20 kt. gusts you can get YANKED off of the water and blown inland, IF you set yourself up for it with poor technique.
