Hyper-Precise Forecast

The 15-minute weather forecast for your next 3 hours

An hourly forecast averages away the moment that matters. Hyperlocal Weather's Hyper-Precise Forecast slices the next 3 hours into quarter-hour steps — an icon, the temperature, the precipitation amount and the wind for every single 15 minutes — with a plain-language Today Outlook right above it. Free on iPhone & Android.

Know when the rain starts and stops

The same engine that powers the quarter-hourly view also draws a minute-by-minute rain curve for the next hour — "Rain stopping in 55 min" — alongside real-time radar. Pair the curve with the 15-minute steps and you know both when it turns wet and how wet it gets.

  • Minute-level nowcast — a countdown to the rain starting or stopping.
  • Real-time radar right next to the curve to confirm what is coming.
  • Forecast summary in plain words above the numbers.

Beyond three hours

Precision hands over to the hourly chart

Once the quarter-hourly window ends, a multi-day hourly chart takes over: precipitation probability and rate, snow, even thunder probability — with one-tap toggles to swap the metric you are tracking.

  • Multiple days in one chart — scroll instead of switching screens.
  • Eight metrics: precip, temp, wind, humidity, UV index, pressure, visibility and coverage.
  • Thunder and snow probability plotted alongside rain.
Today Outlook

The whole day, summed up first

At the top of the Hyper-Precise screen sits the Today Outlook: a plain-language summary of the day plus a comparison against the climate normal for the date — for example, "8 degrees cooler than the 24 June average". Read one sentence, then dive into the quarter hours.

  • Plain words, no jargon — what today actually feels like.
  • Today vs climate normal — see how unusual the day is.
  • One screen — the outlook and the 15-minute steps together.

Why 15 minutes?

Why a 15-minute weather forecast beats an hourly one

An hourly forecast tells you "60% chance of rain between 4 and 5". But real weather does not respect the top of the hour: the shower might land at 4:10 and be gone by 4:40. A 15-minute weather forecast resolves that ambiguity. Hyperlocal Weather's Hyper-Precise Forecast covers the next 3 hours in twelve quarter-hour steps, and each step carries its own weather icon, temperature, precipitation amount and wind direction with speed — a genuinely hyper precise weather forecast instead of an hourly average.

Built for decisions you make right now

Quarter-hourly resolution is made for short-term timing: heading out for a run before the shower, choosing which train to catch for a drier commute, waiting fifteen minutes for better light on a photo shoot, or deciding whether the school pickup needs an umbrella. Because every slice shows wind as well as precipitation, cyclists and drone pilots can pick the calmest window too. When rain is imminent, pair it with rain alerts so the app pings you instead of you watching the screen.

From the next quarter hour to the next two weeks

The 15-minute view is the sharp end of a continuous timeline. When your decision horizon stretches past three hours, the hourly forecast graph carries the same detail across several days, and the radar forecast shows the precipitation actually moving toward you on the map.

  • 0–1 hour: minute-level rain curve — when rain starts or stops.
  • 0–3 hours: the Hyper-Precise Forecast in 15-minute steps.
  • 3 hours–several days: the multi-day hourly chart with eight metrics.
  • Up to 14 days: the daily list with a plain-language weekly summary.

All of it is computed for your exact coordinates from Foreca, Apple WeatherKit and real weather-station observations — the same short term weather forecast quality wherever in the world you open the app.
