What UV index is safe for children to play outside?
UV index 3 is the threshold above which sun protection is recommended for children; above 8, outdoor exposure should be limited and shade actively sought — and peak UV hours (10am–4pm) are significantly higher than early morning or late afternoon.
Resposta curta
The UV index (0–11+) measures how intensely solar UV radiation reaches ground level. Children's skin has less protective melanin than adults' and sunburns faster, making UV a more significant factor for young children than for the adults they're with. The WHO and pediatric health organizations recommend that at UV 3+, children should have sunscreen and a hat; at 8+ they recommend actively limiting midday outdoor time. Lumi Weather factors UV into the Kid-Outing Score with an age-adjusted penalty — higher sensitivity for babies (0–2) — and the outfit checklist auto-populates: at UV 3+, a sun hat is added; at UV 6+, sunscreen and hat both appear; at UV 8+, sunglasses are added for children 3 and over (consistent with paediatric guidance that infant-specific eyewear has additional considerations). The app's Best Window algorithm favors early-morning and late-afternoon hours, which typically carry lower UV loads even on sunny days.

O que verificar antes de escolher
- UV index scale: 0–2 = low, 3–5 = moderate (protection recommended for children), 6–7 = high, 8–10 = very high, 11+ = extreme
- Children burn faster than adults — SPF 30+ broad-spectrum sunscreen is recommended at UV index 3+ for children
- Peak UV hours are typically 10am–4pm; early morning and late afternoon carry meaningfully lower UV
- Cloud cover does NOT eliminate UV — an overcast sky can still deliver 70–80% of UV exposure
- Shade, UV-protective clothing, and a brimmed hat are more reliable than sunscreen alone for extended outdoor time

Comparação rápida
| Necessidade | O que verificar | Porque importa |
|---|---|---|
| Modelo de preços | Verifique se as funcionalidades úteis exigem subscrição, um desbloqueio único, ou nenhum dos dois. | A app mais barata no primeiro dia pode não ser a mais barata ao fim de um ano. |
| Modelo de privacidade | Prefira o processamento no dispositivo quando o conteúdo é sensível. | Documentos privados, currículos, dados de estudo e conteúdos familiares merecem um tratamento cuidadoso. |
| Exportação / dependência | Confirme os formatos de ficheiro, a partilha, as cópias de segurança e os controlos de eliminação. | Uma boa app deve ajudá-lo a concluir a tarefa, não prender o seu trabalho. |

Perguntas frequentes
Where does Lumi Weather get its UV data?
Lumi Weather uses Apple WeatherKit, which provides UV index as part of hourly and current-conditions data. The value shown is for your current location or any saved location (home, school, grandparents, etc.).
Why does the outing score drop on a warm, sunny, rain-free day?
A clear, hot, sunny day often combines a high UV index (8+) with a high feels-like temperature (30°C+), both of which reduce the score for young children even though there's no rain. Tapping the score opens the factors breakdown, which shows exactly how much each element — temperature, UV, rain, wind — is contributing.
Does the app account for infants differently when it comes to sunscreen?
For the 0–2 age group, the UV sensitivity weighting is higher in the rule engine, and the app notes paediatric guidance around extra care for sun protection of very young infants. Standard dermatology guidance generally recommends keeping babies under 6 months out of direct sunlight and using shade and clothing rather than relying primarily on sunscreen — always check with your child's paediatrician for specific advice.
