Forecast data

Key information

• Station name: Portsmouth
• Station ID: 1028
• Estuary/harbour: Tide
• Highest level on record: 2.82m on 06 December 2013
• Site datum: 0.00mAOD (what does this mean?)

How are tide levels in coastal and estuary areas measured?

Tide levels in coastal and estuary areas are shown in metres above mean sea level, or ordnance datum (mAOD).

Monitoring stations in these locations do have their own datum - a height in metres fixed relative to mean sea level. But, because of their location, these stations usually have the same datum as actual mean sea level. So it's expressed as zero metres.

How often are tide levels in coastal and estuary areas measured?

We use measuring stations like this one to collect water level data, usually once or twice a day. We collect data more frequently when there's a greater risk of flooding. That's why the graph might show a short time lag since the last measurement.
