OnPoint Sub-Seasonal Forecast | Up to 46 Days | Global Coverage | Daily / Weekly Format

OnPoint Sub-Seasonal Forecast delivers daily and weekly outlooks up to 46 days ahead, derived from ECMWF’s ensemble system and updated daily. The product provides both historical and forecasted atmospheric and oceanic conditions, with daily and weekly averages for key parameters like air temperature, wind, solar radiation, precipitation, and snowfall. In addition, daily historical forecasts back to October 2023 and weekly back to January 2014 are also available upon request.

Designed for advanced planning, this dataset enables users to analyze trends, anomalies, and probabilities for critical weather variables—supporting more informed, mid-range decision-making across business and research applications. By integrating sub-seasonal forecasts, organizations could gain agility in navigating weather-driven uncertainty, while researchers could enhance climate resilience strategies.

Is OnPoint Sub-Seasonal Forecast Data Right for You?

OnPoint Sub-Seasonal Forecast's time range bridges the gap between Short -Mid Range weather forecasts (up to 15 days) and Seasonal Forecasts (7 months ahead), making it valuable for sectors that need to plan several weeks in advance, such as energy, agriculture, water management, and disaster preparedness.

Consider sub-seasonal forecasts if your business:

- Requires planning 2-6 weeks ahead. For longer timeframe decisions, consider OnPoint - Seasonal Forecast.
- Operates in weather-sensitive sectors.
- Needs probabilistic insights to manage risk or capitalize on trends.
- For daily or short-term operational decisions, consider OnPoint Forecast: Short-Mid
Range or OnPoint Forecast Ensembles.
