The Fitzroy barometer in glass and solid wood — invented by Admiral FitzRoy, captain of HMS Beagle in the 19th century. Predicts weather fluctuations up to 48 hours in advance by observing atmospheric pressure variations. Dimensions: 11.5 × 6.5 cm. A functional decorative object, between science and craftsmanship.
Weather forecast up to 48 hours
By observing variations in the liquid level in the glass tube, you can anticipate imminent weather changes up to two days in advance.
Invention of Admiral FitzRoy
Created in the 19th century by Admiral Robert FitzRoy, captain of the famous British ship HMS Beagle — the same one that transported Charles Darwin.
Solid wood base
Warm and natural base that elegantly contrasts with the transparency of the glass — a timeless aesthetic for any interior.
11.5 × 6.5 cm — compact
Small and discreet format — fits on a desk, shelf, or windowsill without clutter.
Functional and decorative
An authentic scientific object as much as a decorative piece — for meteorology enthusiasts and lovers of beautiful objects.
Original gift
Ideal for a science or navigation enthusiast, vintage decor lover, or to enrich an office with an object rich in history.
FitzRoy's Legacy — predicting the weather without electronics
The Fitzroy barometer is based on a simple and unchanging principle: variations in atmospheric pressure influence the liquid level in the glass tube. When the pressure rises, the liquid level drops — a sign of good weather. When the pressure drops, the liquid rises in the spout — announcing disturbances. No batteries, no screen, no connection — just physics at the service of weather forecasting since the 19th century.

How to read a Fitzroy barometer: observe the liquid level in the spout (upper tube). Low level = high pressure = stable good weather. High level = low pressure = upcoming disturbances. The change in level over 12 to 24 hours is more indicative than the absolute position — a rapid rise signals rain, a rapid drop signals improvement.

Frequently Asked Questions
How does a Fitzroy barometer work?
The Fitzroy barometer works on the principle of atmospheric pressure: when the pressure rises (good weather), the liquid level in the upper spout drops. When the pressure drops (impending disturbances), the liquid rises in the spout. It can anticipate weather changes up to 48 hours in advance.
Who invented the Fitzroy barometer?
Admiral Robert FitzRoy, captain of HMS Beagle — the famous ship that carried Charles Darwin on his voyage to the Galápagos in the 19th century. FitzRoy was also one of the pioneers of modern meteorology and founded what would become the British Met Office.
Does it need to be calibrated or refilled?
The Fitzroy barometer comes pre-filled with a colored liquid. No special maintenance is required — simply place it in a stable location, away from direct drafts and excessive heat that could distort the readings.
What is its meteorological accuracy?
The Fitzroy barometer is a weather trend indicator, not a precision instrument like a calibrated digital barometer. It is particularly reliable for detecting rapid pressure changes — and thus imminent weather shifts — over 12 to 48 hours.
