Rhine · Danube · climate & hydrology

Climate and hydrology for the Rhine and the Danube.

For river cruise operators, charterers and shippers: we read what feeds both rivers — snowpack and glacier trends, precipitation, seasonal climate outlooks — and turn it into one directional call, up to twelve months ahead.

The signal chain — reading the season early
From ice to water: Alpine snow & ice → melt → river flow → your navigation season.

03 · How it worksThree steps, one seasonal read.

No dashboard to learn. No model to configure. You get a directional call and the evidence behind it.

STEP 01

Pick your window

Your river, your trading season, your decision date — a charter window, a capacity block, a pricing cycle.

→ You get: the relevant monitoring set
STEP 02

Get the seasonal read

One directional judgement — favourable, corrective, or defensive — with the climate and hydrological evidence behind it.

→ You get: one call + its evidence
STEP 03

Act before the market does

Capacity, rerouting, pricing and deployment decisions moved earlier — while they are still cheap to change.

→ You get: lead time your competitors don't have

04 · The outputDon't take our word for it. Read the output.

Two report formats ship every cycle: a season-level outlook, and a decision-grade call for the next 3–6 months.

05 · IntegrateBuilt to drop into operations, not just an inbox.

A reading only helps if it reaches whoever reroutes a sailing. attuneline ships the same signal three ways — choose what your stack already accepts.

Pre-launch demo. Full UI planned here; the live API, auth and docs land before launch. See the API page for the planned surface. Explore the API →

06 · PricingPriced to be tried, not to be negotiated.

Start at the price of a coffee. Add the industry read when it has already paid for itself once. We start from the same free public data everyone else does — you pay for the reading, not the access.
