How to adjust by scenario

Commute / driving Pair the heat signal with OneMotoring roadworks/closure checks, especially overnight KPE / CTE / Fort Canning windows; add 10–20 minutes buffer.
i Light opening night 5 Jun looks relatively friendly weather-wise, but the main cost is opening-night crowds. Pick 2–3 stops and one sheltered exit point.
Family weekend Use Festival of Biodiversity, Gardens by the Bay Children’s Festival, or museums as the core plan on 6–7 Jun; keep parks as early short blocks.
Outdoor sport / coast Avoid midday heat and thundery-shower windows. If thunder is close, leave open areas, exposed boardwalks, and high viewpoints.

3 rules from today to the weekend

  • For day plans, check heat + lightning; for night plans, check return route + crowds.
  • Free events are not zero-cost: queue time, walking, food, and transport still count.
  • Treat social posts as leads only. Verify weather, dates, hours, and road closures with official pages.
