Kayaking on the Waimakariri River

River and Weather Information

 

Before heading away on your trip it is critical that you check the weather forecast and the river levels. These sites are up to date and accurate and will help greatly when planning your training.

 

Step One

 

 Use the Ecan links below to check the following limits and remember to never get on a rising river! 

 

Waimakariri Esk: This gauge is 2.5km downstream of Gorge Entrance and measures the height of. the river. 

 

This gauge should be a maximum of 0.7m and DROPPING

 

Waimakariri Otarama: This gauge is located 5km upstream of Woodstock and measures the volume of water through the Gorge. 

 

This gauge should be a maximum of 150 cumecs (m³/s) and DROPPING

 

Waimakariri Gorge: This gauge is located on the Gorge Bridge and measures the height of the river. 

 

This gauge should be a maximum of 1.8m and DROPPING

 

Old Highway Bridge: This gauge is next to the State Highway 1 Bridge (near the coast) and gives the cumecs (m³/s) reading in town and the progress of water down the river.

 

 

Step Two 

 

Use the 'Weather Information' links below to check the following:

 

Rainfall/Precipitation - Look for consistency and quantity. 5mm per hour (or more) is a lot especially if it keeps consistent. With the radars look for the colours associated with larger rain quantitiy. (Red is usually the heaviest rain). Rainfall means rising river!

 

Wind Speed - Check the high country and Arthur's Pass NP forecast. Ensure wind speed is less than 55kmph.

Note that the speed is often the predicted average and does not account for gusts of higher speed.

 

Temperature - The lower the temperature, the colder! Generally rule is 0.7 degrees Celsius per 100m elevation change.

So if the AP National Park forecast @ Avalanche Peak (1833m ASL) is -5°, then the temperature at the Mt White Bridge 'put in' (550m ASL) would be 4.8° Celsius. Of course this is a rough estimate but is a good place to start. 

There isn't a specified limit on temperature but will help you prepare for the conditions (Although we hope you are always prepared with extra warm gear anyway).

METVUW - Metvuw is an alternative website with data collected from the USNWS

Comparing more than one chart provider can increase probability of the forecast
