If you're trying to figure out whether to take an umbrella in Potosí, Bolivia, or whether to postpone an outdoor plan, this page gives a direct answer. We show today's rain probability hour-by-hour, expected precipitation amounts in millimetres, and a 7-day outlook that highlights the rainiest day, the driest day, and any thunderstorm risk in Potosí. The forecast is re-fetched from Open-Meteo each time you open the page, and every day carries a confidence band derived from forecast lead time and how variable the forecast itself is — near-term days are safe to plan on, while rain timing further out can still shift by several hours. For travellers, this page is the fastest way to plan around showers in Potosí; for residents, it's a quick rain check that beats opening a generic weather app. Pair it with our "best day to visit Potosí" page if you want a full ranked recommendation across the week.
Probability alone is not a decision. In Potosi we treat under 20 % as go, 20–50 % as carry-a-layer, and over 50 % as plan indoors — and we pair every figure with expected millimetres, because 60 % chance of 0.3 mm drizzle is a completely different day from 40 % chance of 12 mm. A confidence band based on forecast lead time is shown so you know how much the timing could still shift.
