Is today good weather for hedge trimming?

The quick answer

GoodDayTo checks whether your complete selected hedge-trimming job stays dry enough, calm enough, cool enough and inside daylight. The first result remains simple: GO, WAIT or NOT TODAY, the activity name, the best complete window and one memorable explanation. The detailed weather facts sit below that result so rain limits, gusts, heat and daylight support the decision without crowding the first screen.

This is stricter than a general gardening score. Moving branches and cuttings become less predictable in gusts, wet foliage and ground can change the practical setup, and powered cutting work needs good visibility. A calm first hour is not useful if the final hour becomes rainy or much windier, so the scorer evaluates every requested hour together.

How the whole-job score works

Choose one, three or five hours. GoodDayTo searches the hourly forecast for a continuous block of that full length. It does not silently shorten a three-hour job to one attractive hour. Each candidate block receives an activity score for apparent temperature, rain probability, measured precipitation, sustained wind, gusts, UV and daylight. Safety and task-specific caps are then applied to the complete block.

Why rain is checked across every selected hour

The rain rule is intentionally sensitive because the tool cannot distinguish a hand-tool tidy-up from a powered hedge-trimmer job. At least 0.2 mm across the selected job or a 60% hourly rain probability caps the result at 45, which is NOT TODAY. At least 0.1 mm or 35% probability caps it at 70, which is WAIT. A fully dry block can remain eligible for GO.

These values are planning guardrails, not claims that a particular tool becomes safe or unsafe at a universal rainfall amount. Forecast precipitation also does not reveal whether leaves, handles, extension connections or the ground are already wet from earlier rain, dew or irrigation. Inspect the actual work area and follow the tool manufacturer’s instructions.

Why wind and gusts have their own limits

Average wind describes the broader flow, while gusts describe shorter peaks. Hedge work can be affected by both: branches move, the cut line becomes harder to judge, loose cuttings blow toward paths or neighbours, and balance can become less predictable. GoodDayTo therefore checks the strongest sustained wind and gust anywhere in the chosen job.

Sustained wind at 22 km/h or gusts at 35 km/h prevent GO. Sustained wind at 30 km/h or gusts at 45 km/h cap the job at NOT TODAY. They are conservative planning thresholds, not manufacturer ratings and not professional arboriculture rules. Exposed gardens, tall hedges and ladder work may need a much calmer day.

Heat, UV and daylight

Hedge trimming can mean repeated lifting, reaching and carrying cuttings. Apparent temperature reaching 30°C prevents GO; at 35°C the activity is capped at NOT TODAY. UV remains visible in the details because a dry job in direct sun can still be tiring. GoodDayTo may prefer an earlier, cooler block even when the whole afternoon is dry.

The default activity requires daylight. After dark, the score is capped at NOT TODAY because the model cannot confirm task lighting or visibility around blades, cables, branches and footing. An illuminated commercial setup is outside this household planning model.

Which duration should I choose?

• 1 hour: a small tidy-up where setup, cutting and clean-up genuinely fit inside one hour.
• 3 hours: the useful default for an ordinary garden hedge, including clearing cuttings.
• 5 hours: a half-day job. Use it only when you truly need five continuous forecast hours; it is deliberately harder to find a safe-looking complete block.

The selected duration controls both the answer and better-later search. If a dry morning supports only one hour but rain reaches the third hour, a three-hour request will not borrow the one-hour GO. Planner requests, saved routines, activity rankings and this page all use the same shared scoring engine.

A practical example

Suppose 09:00 and 10:00 are mild and calm, but the 11:00 forecast reaches 0.2 mm of rain. A three-hour hedge job is capped at 45 and returns NOT TODAY because the rain falls inside the requested job. A one-hour request may still find a GO at 09:00 if every other condition is suitable. That is not a contradiction: the plans have different durations.

If the next morning offers three dry daylight hours with light wind, moderate temperature and no stronger safety cap, GoodDayTo can recommend that later block. The result should say why it is better rather than merely lowering today’s score.

Measured factors and honest limitations

• Hourly rain probability
• Hourly precipitation amount
• Sustained wind
• Peak gusts
• Apparent temperature
• UV index
• Daylight
• Continuous duration

GoodDayTo does not measure leaf wetness, soil firmness, hedge height, branch thickness, slope, ladder condition, extension-lead routing, residual-current protection, blade condition, battery condition, noise, experience or protective equipment. It does not know where overhead or hidden services are. Those are real-world checks, not missing weather fields.

The UK Health and Safety Executive notes that unsuitable electrical equipment can create danger in wet surroundings and separately warns that contact with overhead power lines can cause fatal or severe injury. OSHA lists cuts, amputations, hand injuries, eye injury, hearing loss and ergonomic hazards in landscaping work. These sources explain why a weather verdict must remain subordinate to equipment instructions and a real inspection.

Wildlife and local rules

The weather tool never decides whether cutting is lawful or appropriate. Inspect the hedge carefully for active nests and protected wildlife. Seasonal restrictions, noise rules and property obligations differ by country and sometimes by land type. For example, official England guidance says not to disturb active wild-bird nests and describes separate agricultural hedgerow cutting rules. That is an example of why users must check the rules that apply at their exact location; it is not a worldwide calendar.
