Methodology

How Should I Mow My Lawn works

Should I Mow My Lawn is a practical decision tool. It does not predict the exact state of every blade of grass. It combines weather data, mowing heuristics, and local context to estimate whether cutting now, later, tomorrow, or this week looks sensible.

What goes into the recommendation

Each recommendation starts with current and forecast weather from Open-Meteo. We look at rain risk, recent and incoming precipitation, wind, temperature, daylight, and the likely drying window around the lawn.

We also factor in mowing-specific signals that matter in the real world: whether grass is likely to be wet, whether the ground may be soft enough to rut, whether heat or wind could stress the lawn or the person mowing, and whether there is enough daylight to finish safely.

What is heuristic and what is exact

Forecast times, temperatures, precipitation probabilities, and daylight windows come from structured weather data. The mowing verdict itself is heuristic. It reflects a rules-based interpretation of those inputs rather than a guarantee that your lawn is safe to mow.

That matters because two lawns in the same city can dry at different rates depending on shade, soil, drainage, mower setup, and grass type. The app estimates likely suitability; your own visual and physical checks still decide the final answer.

Why location-specific pages differ from general advice

Advice pages explain broader topics such as wet grass, seasonal mowing, or cutting height. Location pages and the personalized app flow apply that guidance to a specific forecast and a saved location. That is why a general article can say “usually wait after heavy rain” while a city page can still show a possible mowing window later in the week.

What the app cannot know perfectly

The app cannot inspect your lawn surface, mower blade sharpness, drainage, slope, or local restrictions. It also cannot see microclimate effects such as a shaded back garden staying wet longer than the nearest weather grid suggests.

Use the recommendation as a weather-aware screening tool, then confirm the lawn is dry enough, the ground is firm enough, and conditions are safe enough before mowing.

Data sources and editorial approach

Weather data is supplied by Open-Meteo. Editorial advice pages use publisher-written summaries backed by cited lawn-care sources and are reviewed when guidance changes or a page needs correction.

Safety and limitations

Recommendations can be wrong, incomplete, or out of date by the time you act on them. Always follow your equipment guidance, local restrictions, and any official weather warnings. Do not mow in thunderstorms, on waterlogged ground, or when visibility and footing are poor.
