Xweather Optimize

Local forecast accuracy that drives operational performance

  • 50% more accurate on average
  • Managed sensor service
  • Calibrated confidence limits

Machine learning forecasts with calibrated confidence limits, powered by ground-truth observations from sensors deployed and maintained at your sites.

Measurable forecast improvement within months

Xweather Optimize pairs on-site sensors with a dedicated machine learning model for each location. The model typically needs three to six months of observations before delivering measurably improved local forecasts. Accuracy continues to improve as more data arrives.

A dedicated forecast for each location

Every Xweather Optimize deployment combines wireless IoT sensors with a dedicated machine learning forecast model trained on that site's observed data. Forecast accuracy improves continuously as the observation dataset grows.

  • Site-specific models
  • Wireless sensors
  • API and dashboard

Optimization at every site

Forecast accuracy tuned to each location drives better operational decisions daily.

Fewer costly large errors

Dedicated models reduce the extreme forecast misses that cause the most damage.

No operational burden

A managed service handles sensor deployment, monitoring, maintenance, and data quality. Installation is straightforward, with no extensive infrastructure, cabling, or specialist contractors required.

Confidence in every forecast

Calibrated confidence limits quantify forecast uncertainty, giving operations teams clear parameters for decisions.

Always the latest information

Xweather Optimize refreshes forecasts as new sensor observations arrive, rather than waiting for the next global model cycle. Calibrated confidence limits show both the forecast value and the range of likely outcomes at 50%, 80%, 95%, and 99% levels.

  • Forecasts update every 15 minutes
  • Calibrated confidence limits with range of likely outcomes
  • Fresh forecasts on demand

Hyperlocal forecasting for energy and infrastructure

Xweather Optimize serves operations where small forecast errors create large cost consequences. Each use case depends on accuracy at a specific location.

Dynamic line rating

Dynamic line rating

Transmission capacity depends on real-time wind speed, direction, and ambient temperature along each span.

Conditions vary dramatically even across short distances, making generic forecasts inadequate for safe capacity increases.

Xweather Optimize captures these local variations using AtmoCast sensors at critical spans, providing the precise, site-specific data that dynamic line rating calculations require to maximize grid throughput safely.

District heating

District heating operations

Weather is the single biggest factor affecting daily heating demand. Even small temperature forecast errors translate directly into wasted energy or supply shortfalls.

Xweather Optimize delivers hyperlocal temperature forecasts up to 50% more accurate than traditional sources, enabling district heating operators to fine-tune supply temperatures and reduce fuel consumption.

Building energy management

Building energy management

Predictive HVAC control depends on accurate short-term temperature forecasts to pre-cool or pre-heat buildings ahead of weather shifts. Generic city-level forecasts introduce errors that reduce efficiency gains.

Xweather Optimize provides building-level temperature forecasts that enable AI-based control systems to respond to actual conditions at each facility, reducing energy consumption while maintaining occupant comfort and supporting sustainability targets.

Reduce large forecast errors

59% fewer errors greater than 2.5°C in 24-hour forecasts at customer sites.

Sensors, models, and confidence limits

Xweather Optimize combines three elements into a single managed service: precision sensors, a dedicated forecast model for each site, and calibrated confidence limits that quantify uncertainty for operational decisions.

  • AtmoCast sensors

    Wireless IoT sensors with industry-leading accuracy, easy installation, and hassle-free operation. Measures air temperature, wind speed, wind gusts, wind direction, rain accumulation, atmospheric pressure, humidity, dew point, and hail. The same sensor technology used on the Mars Perseverance rover.

  • ML forecasts

    A dedicated machine learning model trained on each site's observed data. Models improve continuously as more observations arrive and refresh on demand, delivering forecasts calibrated to local conditions.

  • Confidence limits

    Calibrated probability bounds at 50%, 80%, 95%, and 99% confidence levels. Operations teams see both the forecast value and the range of likely outcomes, enabling decisions proportional to the certainty of the prediction.

Everything from a single provider

Xweather Optimize delivers sensors, forecasts, data quality management, and ongoing maintenance from a single provider. Vaisala manufactures the sensors. Xweather deploys, monitors, and maintains them. A dedicated forecast model is trained on each site's data and delivered through a unified dashboard and API.

This integrated approach eliminates the complexity of sourcing sensors from one vendor, forecasts from another, and building integration and data quality processes internally. No combination of separate providers can replicate it.

Frequently asked questions

Through Xcast sensors and supported stations, Optimize can access more than 30 weather and environmental parameters via the shared Xweather Observe framework, including core variables such as air temperature, wind speed, humidity, and other surface conditions. Forecasting in Optimize focuses on parameters where hyperlocal accuracy has the largest operational impact, particularly air temperature and wind speed, but the platform also provides broader condition and forecast data for up to ten days at any point globally via its forecast and condition endpoints.
