Christchurch Surf Check is made using:

Christchurch Surf Check, v3.0

v3.1 released 2 July 2024 (Improvements to swell interval forecast data, by using AI modelling to compare forecast data to the LPC buoy data.)

v3.0 released 18 January 2024 (Switched to using Storm Glass AI for swell and wave prediction data. This is able to provide more accurate data that takes into account wind swell and ground swell arriving at each location, as well as using multiple sources to give the most accurate forecast possible.)

v2.8 released 27 November 2023 (Updated data source for the LPC buoy. Buoy data now updates in near real-time rather than every hour.)

v2.7 released 15 June 2023 (An automated report for the best time and location tomorrow now posts to the Chch Surf Facebook page every evening at 5:30pm.)

v2.6 released 13 June 2023 (Plain text surf reports for each day are now displayed above the forecast chart. These are automatically generated, unless a manual report exists to display instead.)

v2.5 released 5 June 2023 (Major update to the wave height algorithm, to more accurately reflect wave heights through each hour of the forecast. Each hour forecast also now includes a rating from 0 to 5 stars, which takes in to account the waves, swell, tide and wind data for that time, as well as recent wind conditions and the direction of the coastline. More detailed star ratings can be shown by tapping on the forecast chart, which will display the extra data just above the chart).

v2.4 released 3 June 2023 (User generated surf reports now show on front page of site for the first 8 hours, added the ability to share photo galleries to Facebook).

v2.3 released 27 May 2023 (added the ability to 'heart' user generated surf reports, and show number of views).
