What this is

Mowdar is a free tool that interprets weather forecast data to suggest when conditions suit mowing, and reports modelled soil temperature. It is provided as it is, for personal use, with no charge and no account.

What it is not

It is not a weather service, and it is not professional agronomic advice. The forecasts underneath it are forecasts: they are sometimes wrong, and they get less reliable the further out they go, which is why the site marks its own confidence.

Soil temperature here is modelled, not measured. It is derived from a weather model rather than a probe in your garden. Treat it as a good estimate for the area, not a reading from your lawn.

Your judgement comes first

You know things the model does not: that one corner never drains, that the slope is steeper than it looks, that there is a wasp nest by the shed. Look at the lawn before you start. If the site says conditions are good and the ground is plainly soaking, believe the ground.

We are not liable for damage to your lawn, your mower, or anything else resulting from decisions you make using this site. Operate machinery safely and according to its manufacturer's instructions.

Considerate hours are not legal advice

The site discourages mowing at unsociable hours. That is etiquette, not law. There is no UK statute setting mowing hours; councils act on persistent noise nuisance under the Environmental Protection Act 1990. Nothing here tells you what is or is not lawful where you live.

Availability and changes

We make no promise that the site will be available, and it depends on third-party services that can fail. We may change or withdraw any part of it. Where a data source is unavailable, the site will say so rather than guess.

Content

The articles and the model are ours. You are welcome to link to anything here and to share the result cards. Do not republish the articles wholesale. Forecast data is supplied by Open-Meteo under its own terms.

Law

These terms are governed by the law of England and Wales. Contacthello@mowdar.com.
