Gardening is a comfortable-weather pursuit, and the score reflects the mild, gentle conditions that suit both the gardener and the plants. Temperature leads, with a moderate band scoring best: warm enough to work comfortably and for the soil to be workable, but not so hot that both you and freshly disturbed plants suffer. Unlike most activities, light rain is not penalised heavily and can even be beneficial, since damp soil is easier to work and newly planted seedlings appreciate the moisture, which is why the score treats a little rain kindly while still marking down heavy downpours that turn beds to mud.
The relationship between rain and gardening is more nuanced than for most activities, and the score captures this. A light shower or recently moistened soil is often ideal for planting and transplanting, helping roots settle in without the stress of dry ground, so the score actually peaks with a touch of moisture rather than bone-dry conditions. Heavy or persistent rain is a different matter, compacting soil, making it too wet to work without damaging its structure, and drowning young plants, so the score falls away as rain intensifies. Experienced gardeners watch not just today but the recent pattern, knowing that working wet clay soil can harm it for a whole season.
Wind and sun round out the score because they affect both the work and the plants. Strong wind makes delicate tasks difficult, dries out soil and exposed roots, can damage tender new growth, and simply makes a day in the garden less pleasant, so the score rewards calm conditions. The sun and UV factor is a gentle reminder rather than a major penalty: gardening often means hours outdoors, frequently bending over beds with the back of the neck exposed, so the score nudges down at high UV to prompt sensible sun protection. A mild, calm, lightly overcast day is, for many gardeners, close to perfect working weather.
The score tells you about today's working conditions, but good gardening also means reading the weather ahead. Before planting tender things out, gardeners watch for the risk of late frost, which can undo a day's work overnight. Before sowing, they consider whether the soil is warm enough for seeds to germinate rather than rot. Before a dry spell, they water and mulch; before heavy rain, they hold off on tasks that need dry soil. Use the score to pick comfortable, productive days for the hands-on work, and pair it with an eye on the forecast for frost, heat and rain, which together shape the success of everything you plant.
