Seychelles: Average precipitation in depth (mm per year)

Key figures

What the numbers say

In 2022, Seychelles' average precipitation in depth (mm per year) did not change 0 on 2021 (from 2,330 to 2,330).

Across the 30 yearly changes before that (1992 to 2021), the average change was +0 and a typical year strayed about 94.54 from that (the standard deviation). This year's change was 0.0 standard deviations above that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 360 in 2001 and the biggest yearly fall was 360 in 2000. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2013 to 2022 there is no clear straight-line trend: a straight line explains less than 1% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

Worked out from the yearly values above. How the checks work: standard deviation, z-scores and straight-line trends.

How it compares

In 2022, Seychelles had the 20th highest value of the 180 economies reporting that year. Higher is not always better: for some indicators the lowest value is the one to aim for. See the full ranking.

What this measures

Average precipitation is the long-term average in depth (over space and time) of annual precipitation in the country. Precipitation is defined as any kind of water that falls from clouds as a liquid or a solid.

Limitations: The data are collected by the Food and Agriculture Organization of the United Nations (FAO) through annual questionnaires. The FAO tries to impose standard definitions and reporting methods, but complete consistency across countries and over time is not possible.
