This template employs intricate features of template syntax.

You are encouraged to familiarise yourself with its setup and parser functions before editing the template. If your edit causes unexpected problems, please undo it quickly, as this template may appear on a large number of pages.
Remember that you can conduct experiments, and should test all improvements, in either the or your user space before changing anything here.

This template is used on many pages, and changes to it will be widely noticed. Please test any changes in the template's /sandbox or /testcases subpages, or in a user subpage, and consider discussing changes at the talk page before implementing them.

For questions, see the talk page. For shorter forms, see below: Concise forms.

You can enter data in imperial units or metric units or both.
You may remove unused fields.
All fields are optional, except for location and source 1.
Year values will be calculated provided that all month values are provided.
Please use the same precision for all values in a row, e.g. if Ion is 0 and Chw is 0.3, then use 0.0 for Ion.
If using multiple tables, or there are pictures or infoboxes higher up on the page, please verify that the template does not overlay, or get overlaid by, other objects used in the article. Please test your changes with several different skins, browsers, and browser window sizes. If necessary use {{Clear}} before the climate section, or <div style="width:50%;"> before the table, and </div> after.
A source should always be provided - if, however, there is no source, you can add |date=Month Year to the template, which will help sort the article into a subcat of Category:Articles with unsourced statements.

Imperial-only empty syntax

Will convert and display metric values automatically.

View and edit links

When this template is used in template space, it may be desirable to provide view and edit links to the template (similar to a navbox). This can be be accomplished by setting the name parameter to be the name of the template.

| name = {{subst:PAGENAME}}

Concise forms

There are shorter templates that invoke {{Weather box}} with 36 condensed parameters:

{{Weather box/concise C}} - for coding only average uchaf and isaf temperatures, and dyddodiad, in Celsius degrees and millimetres.
{{Weather box/concise_F}} - for coding only average uchaf and isaf temperatures, and dyddodiad, in Fahrenheit degrees and inches.

Similar templates

{{Climate chart}} - which displays climate information in a graphical chart format.
