Important! The levels for this location are measured relative to sea level, not relative to the riverbed. The levels shown here do not, therefore, necessarily represent the actual depth of the water.

This is a tidal level, measured from mean sea level rather than from the river bed. It can, therefore, be negative, and does not give any indication of water depth. Tidal levels are not necessarily updated frequently, and may not reflect tidal movements throughout the day.

The usual range of the Llandudno Monitoring Station is between -3.73m and 4.34m. It has been between these levels for 90% of the time since monitoring began.

The typical recent level of the Llandudno Monitoring Station over the past 12 months has been between -3.91m and 4.86m. It has been between these levels for at least 150 days in the past year.

Darker blue shaded areas on long term data indicate maximum and minimum levels for the date (you may need to zoom in closer to see them).

Long term data may have gaps where the API data was not available.

Download long term data as csv

Note: CSV data will include any outlying values that have been ignored by our graphing system as probably erroneous (eg, because they are ridiculously high compared to the values either side of them). It is your responsibility to filter these out if necessary.

Important! If you are planning to retrieve the csv data automatically, you must read and understand the limitations on the data and its availability.
