Beaufort Scale Day

May 7, Wednesday

Beaufort Scale Day is celebrated annually on May 7. This holiday is dedicated to the unique system for assessing wind strength, developed by Admiral Francis Beaufort in the early 19th century. The Beaufort scale is widely used in meteorology, navigation, and other fields where understanding and measuring wind speed is important.

Who was Francis Beaufort?
Francis Beaufort (1774–1857) was a British admiral and hydrographer who made significant contributions to the development of maritime navigation. In 1805, he proposed a scale to estimate wind strength by observing its effect on a ship's sails. Over time, the scale was adapted and expanded for use on land and for scientific purposes.

What is the Beaufort scale?
The scale includes 13 levels — from 0 (calm) to 12 (hurricane). Each level is accompanied by a description of visible wind effects:
- calm — smoke rises vertically
- light breeze — leaves barely stir
- moderate wind — wind is felt on the face, thin branches move
- strong wind — trees sway, walking is difficult
- hurricane — significant damage, extremely dangerous conditions

How is Beaufort Scale Day celebrated?
- reading about Francis Beaufort and the history of his invention
- learning how to determine wind strength using the scale
- observing the weather and trying to assess wind levels independently
- sharing photos and observations on social media with thematic hashtags
- conducting lessons or lectures on meteorology and safety during strong winds

Why is this day important?
Beaufort Scale Day reminds us of the importance of science and observation. The scale helps people understand the environment, take precautions during storms, and teach children and adults to navigate weather conditions.
