On the record: For 1991–2025, we checked the eleven days around this date. Budapest’s lowest daily average was 70 cm, in 2015. Today’s reading is 9. 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.
- In portThe ship is in port on this day. Our record holds no river transit for it, so there is no stretch of river to read.
- Not sailingThe ship does not sail on this day. Your itinerary spends it on land, so no river level applies to it.
