We hold no map coordinates for this sailing’s ports, so no map is drawn for it — an empty picture of the wrong rivers would say less than nothing. Every port on this sailing, and its water, is listed below.
Budapest
Day 1 · Friday 11 September · Hungary
The ship is in port on this day. Our record holds no river transit for it, so there is no stretch of river to read.

Day 2 · Saturday 12 September · Hungary
The measured level is under half of Waterlogged's reference line for this ship.
45 cm below Waterlogged’s estimated level
That is how far today's measured level sits below Waterlogged’s estimated level for this stretch — read from the years of record, not a figure from the cruise line.
| Water level now | 15 cm |
|---|---|
| Waterlogged’s Waterlogged's estimated level for this stretch, set from the measured record rather than from any ship's draught. In 35 years of readings, every day of the cruise season below it fell inside a disruption somebody documented at the time. It is a gauge level, not a depth under a ship, and no authority or cruise line publishes it. | 60 cm |
| Normal for 12 September | 201 cm |
On the record: For 1991–2025, we checked the eleven days around this date. Budapest’s lowest daily average was 62 cm, in 2003. Today’s reading is 15. That is below every one of the 385 readings in that window.
Water levels are measured at the Budapest gauge – Observation from Hungary's national water authority.

What to check on the official page: The button below opens the official water-level forecast for this stretch — a simple table, about six days ahead. It shows the level in centimetres at the Budapest gauge, the same way this page shows it, so the numbers line up directly.
Don't be surprised by a negative number: the gauge's zero point sits above the riverbed, so readings below zero are real measurements, not errors.

What the statuses mean — each one is measured against the level we estimate this ship needs
- Far below the lineThe measured level is under half of Waterlogged's reference line for this ship.
- Below the lineThe measured level is below Waterlogged's reference line for this ship.
- Above the lineThe measured level is at or above Waterlogged's reference line for this ship.
- Lock-controlledLocks hold this water at a working level, so low water is far less likely to affect this stretch. Other things still can.
- No line publishedThis is a real reading. There is nothing published to measure it against.
- No reading yetWe watch a gauge on this stretch. No current reading is on file for it.
- No gauge on this stretchWe watch no gauge on this stretch of river. There is no reading for this day and no line to measure one against.

- Not sailingThe ship does not sail on this day. Your itinerary spends it on land, so no river level applies to it.

Each is drawn at its own town's coordinate, which can sit close to the port it serves. Each stretch is coloured by the worst port on it. A gauge level is not the depth of the The navigable channel where ships are meant to pass., not the room under your ship's keel, and not your ship's How deep a ship sits in the water. That depth sets how much water it needs underneath..
