What Is an Hourly Weather Forecast?

An hourly weather forecast breaks the day down into individual hours, giving you a precise picture of how conditions will change from morning to night. Instead of a single high and low for the day, you see the temperature climb and fall hour by hour, the exact hours rain is most likely, when the wind will pick up, and how humidity shifts through the day. It's the forecast you want when timing matters — planning a run, a commute, an outdoor event, or deciding when to mow the lawn before the rain arrives.

Hourly forecasts are generated by the same numerical weather prediction models that produce daily forecasts, but presented at finer time resolution. Modern models update several times a day, so the hourly forecast you check in the morning may be refined by the afternoon as new data comes in.

What Each Hourly Column Tells You

MetricWhat It Means
TemperatureThe actual air temperature expected that hour.
Feels likeWhat it will feel like with humidity and wind factored in.
Precipitation %The chance rain or snow falls during that hour.
WindExpected wind speed and direction.
HumidityHow much moisture is in the air — affects comfort.
💡 The most reliable window is the next 12 hours Hourly forecasts are most accurate in the near term. The next few hours are highly reliable; by 24–48 hours out, the exact hour of a rain shower may shift. Use the hourly view for today and tomorrow, and the daily view for the week ahead.

How Accurate Are Hourly Forecasts?

For the next 6 to 12 hours, hourly forecasts are remarkably accurate for temperature and general conditions. The trickiest element is the precise timing of precipitation — a thunderstorm forecast for 3pm might actually arrive at 2pm or 4pm. This is normal: the atmosphere is chaotic, and pinning a shower to an exact hour two days in advance is at the edge of what's physically predictable. Treat the hourly rain chance as "rain is likely around this part of the day" rather than a stopwatch-precise guarantee.

How to Use the Hourly Forecast

The hourly forecast is your planning tool for the day ahead. Scan it in the morning to spot the best window for outdoor activity, the hour rain is most likely, and when temperatures will peak. For commuters, it answers whether you'll need an umbrella for the walk home. For anyone planning an event, it turns a vague "chance of rain today" into a usable timeline.
