Notes and credits

Be aware that all data is discreet. The lines between data points are an eye guide, they are not an estimate of the value between the connected points!

The River Wyre height at St Michaels is reported by RiverLevels; the typical range is 0.3-5m.

Sunlight hours per calendar month are provided by the Met Office's Bradford station Met Office historic data, the typical range is between 25 and 250hrs PCM. Data is plotted on the 15th of each month, except February, which is plotted on the 14th.

Tide height is that predicted at Fleetwood on the date and time a sample is taken, from tables published by Wyre Council. IMPORTANT all of our samples are taken at high tide, and most on high springs, due to problems with deploying the sampling nets off the slipway at low water - when the nets would drag the bottom.

Sea Temperature (°C) and Wave Energy (kW/m) are daily averages calculated from the data provided by the Cleveleys wavebuoy (default) OR the Morecambe Bay buoy when no data from Cleveleys is available.
