Quick answer: Google launched WeatherNext 3 on September 3, 2026 and says it is being integrated into Google Search, Gemini, Google Maps, Google Maps Platform and Google Cloud. Ordinary users do not install a separate WeatherNext app: check weather in those Google products as usual. Developers can prototype with the Google Maps Platform Weather API, while researchers should note that Google’s public WeatherNext dataset guide still lists WeatherNext 2—not WeatherNext 3—at the time of writing.[1][2][3]
What you can use right now
| What you want to do | Best starting point | What to know |
|---|---|---|
| Check a local forecast | Google Search or Google Maps | WeatherNext 3 is being integrated into Google’s weather experiences; there is no separate consumer download.[1] |
| Ask a weather planning question | Gemini | Ask for a location, date or time window, then verify alerts with the official local weather service.[1] |
| Add weather to an app | Google Maps Platform Weather API | The API covers current conditions, forecasts, history and alerts; a demo key is available for prototypes.[2][4] |
| Analyze raw model data | BigQuery, Earth Engine or Cloud Storage | Google’s public access guide currently exposes WeatherNext 2 datasets. WeatherNext 3 public dataset access is not listed there yet.[3] |
| Make a safety-critical decision | National or local meteorological authority | Google explicitly says to use official agencies for warnings and public-safety advisories.[1] |
How to use WeatherNext 3 in Google Search
You do not need to turn on a WeatherNext setting. Search for a forecast in the normal way, using a precise place and time window.
Try searches such as:
weather in Dubai this eveninghourly rain forecast Lahore tomorrowwind forecast Karachi weekendtemperature in London next 10 daysweather along my route today
For a useful result, include the city or neighborhood, the day, and the variable that matters—rain, temperature, wind or visibility. WeatherNext 3 generates a fresh forecast every hour and supports higher-resolution output than WeatherNext 2, but the displayed consumer forecast may still combine WeatherNext technology with other Google weather systems.[1][2]
How to use WeatherNext 3 in Gemini
Open Gemini and ask a decision-focused question rather than requesting only a temperature.
Copy-paste Gemini weather prompts
- Commute:
Check the hourly rain and wind forecast for [location] between [start time] and [end time]. Give me the driest 30-minute departure window. - Outdoor event:
Compare the weather for [location] on [date] from 3 PM to 9 PM. Flag rain, strong wind, heat and visibility risks. - Travel:
Summarize the 10-day weather outlook for [destination]. Make a packing checklist and clearly separate forecast facts from general advice. - Photography:
Find the forecast cloud cover, precipitation and wind for [location] around sunrise tomorrow. Suggest the most practical shooting window. - Solar work:
Summarize expected cloud cover and sunlight conditions for [location] tomorrow. Do not estimate solar output unless the source provides the required data. - Wind work:
Show the forecast wind speed and direction for [location] by hour. Highlight any period that may require checking an official warning.
Google says WeatherNext 3 adds variables designed for renewable-energy planning, including wind at roughly turbine height, cloud cover and solar radiation. That does not mean every variable will be exposed in every consumer product or region.[1]
How to use it in Google Maps
Use Google Maps normally to inspect a place or plan a trip. Google says WeatherNext 3 is integrated across Maps and its wider ecosystem, but feature presentation can vary by product and rollout state.[1]
A practical workflow is:
- Open the destination or route in Google Maps.
- Check the local weather information shown for the place.
- Compare conditions at your departure and arrival times.
- Recheck shortly before travel because WeatherNext 3 can generate a new forecast every hour.[1]
- Open the relevant government weather service for warnings, closures or evacuation instructions.[1]
Do not assume a more detailed AI forecast replaces an official severe-weather alert. Google’s own launch notice directs users to local meteorological agencies and national weather services for public-safety information.[1]
What changed from WeatherNext 2
| Capability | WeatherNext 2 | WeatherNext 3 |
|---|---|---|
| Forecast refresh/output cadence described by Google | 6-hour increments | New forecast every hour |
| Finest surface resolution described by Google | 25 km grid | Up to 5 km for temperature and moisture |
| Other surface variables | 25 km baseline | Up to 10 km |
| Atmospheric variables such as wind | 25 km | 25 km |
| Real-time satellite input | Previous approach relied mainly on numerical weather-prediction training data | Ingests hourly geostationary satellite mosaics alongside historical analysis |
| Precipitation training | Earlier model approach | Adds NASA IMERG and Google precipitation reanalysis data |
| Renewable-energy variables | General weather variables | Adds 100-meter wind, high-resolution cloud cover and solar-radiation variables |
Google describes WeatherNext 3 as roughly five times sharper overall than WeatherNext 2. The “five times” claim refers to spatial detail in the model comparison, not a promise that every forecast will be five times more accurate.[1]
Why the hourly satellite update matters
Traditional numerical weather-prediction systems are physics simulations that can involve a data lag. Google says WeatherNext 3 directly ingests a global mosaic of geostationary satellite observations and produces a new forecast every hour. The goal is to represent fast-changing rain, surface temperature, storms and fronts with fresher observations.[1]
The model also trains directly on sparse weather-station observations to better represent regional effects such as coastlines, valleys, mountains and local topography. Google positions this as particularly valuable in parts of Latin America, Africa and Asia-Pacific where high-resolution regional forecasting has historically been expensive.[1]
What Google claims about rain accuracy
Google reports that WeatherNext 3 improved the Continuous Ranked Probability Score for medium-range precipitation forecasts by up to 60% against NASA IMERG, 30% against MRMS and 10% against rain-gauge measurements at early lead times.[1]
Those percentages are benchmark results against named datasets and conditions—not a guarantee for your street, a particular storm or every forecast horizon. Treat the model as improved guidance and use official warnings for consequential decisions.
How developers can try Google’s Weather API
The Google Maps Platform Weather API is the practical developer route for current conditions and consumer-facing forecasts. Google documents endpoints for:
- current conditions;
- up to 240 hours of hourly forecasts;
- up to 10 days of daily forecasts;
- up to 24 hours of hourly history;
- real-time weather alerts.[2]
Prototype without billing information
Google offers a Maps Demo Key for limited testing without a credit card. It is for prototypes only, has quotas, and is not designed for production use.[4]
- Open Google’s Maps Demo Key page.
- Sign in with a Google account.
- Select Get a Demo Key and accept the demo terms.
- Use that key with the Weather API examples.
- Before production, create or upgrade to a properly restricted API key with billing and production controls.[4]
Never place an unrestricted production key in public client-side code or a public repository.
Can developers download WeatherNext 3 data?
Google’s WeatherNext forecast-access documentation currently lists operational WeatherNext 2 and WeatherNext 2 Mean datasets in BigQuery, Earth Engine and Google Cloud Storage. It describes real-time and historical fields such as temperature, wind, precipitation, humidity, pressure and vertical velocity.[3]
As of September 3, that page does not list a WeatherNext 3 dataset or starter notebook. Therefore, do not rename WeatherNext 2 endpoints or paths and assume they serve version 3. Use the Weather API for app development, and wait for an explicit WeatherNext 3 dataset or model-access notice if you need raw version-specific output.[2][3]
Best uses—and limits
Good fits
- deciding when to commute or schedule outdoor work;
- travel and event planning;
- weather-aware routing and staffing;
- agricultural planning with professional validation;
- wind and solar generation forecasting;
- research, geospatial analysis and probabilistic risk models.
Do not use it alone for
- evacuation or shelter decisions;
- aviation, marine or emergency operations;
- medical heat-risk decisions;
- flood, cyclone, wildfire or severe-storm warnings;
- any regulated or safety-critical workflow without authoritative data and human review.
Weather remains inherently uncertain. Higher resolution can show more local detail, but it does not remove forecast error.[1]
Frequently asked questions
Is WeatherNext 3 a separate app?
No. Google says WeatherNext 3 is integrated into Search, Gemini, Maps, Google Maps Platform and Cloud. Consumers use those products rather than downloading a standalone WeatherNext app.[1]
Is WeatherNext 3 available worldwide?
Google says the model makes forecasts available across Google products worldwide. The exact display, feature set and rollout can still vary by product and location.[1]
Does Pixel Weather use WeatherNext 3?
The September 3 announcement names Search, Gemini, Maps, Google Maps Platform and Cloud. It does not explicitly name Pixel Weather in its WeatherNext 3 integration summary, so version-specific Pixel Weather support was not confirmed in the reviewed announcement.[1]
How often does WeatherNext 3 update?
Google says it produces a new forecast every hour using recent satellite observations.[1]
Is WeatherNext 3 five times more accurate?
Google calls the global weather picture roughly five times sharper than WeatherNext 2 because surface resolution can improve from 25 km to as fine as 5 km. That is a resolution comparison, not a universal five-times-accuracy guarantee.[1]
Can I get a free Weather API key?
Google offers a no-cost Maps Demo Key without billing information for limited prototyping. It has quotas and is not intended for production.[4]
Is raw WeatherNext 3 data in BigQuery or Earth Engine?
No WeatherNext 3 dataset was listed in Google’s public access guide when this article was checked. The guide currently lists WeatherNext 2 datasets.[3]
Should I trust it during severe weather?
Use it as supplementary forecast information. For severe-weather warnings and public-safety decisions, Google says to refer to the responsible local meteorological agency or national weather service.[1]
