With the recent update, we have incorporated a 1-hour forecast option into the Compare Forecast feature. In light of this enhancement, it's the perfect time to offer a more detailed insight into the functionality of this powerful tool!

Let's start with the basics

The Compare Forecast feature allows us to compare forecasts from different models, thus providing a holistic and more nuanced understanding of the weather patterns for a specific location. This is especially useful for professionals who need more comprehensive data or for users who wish to understand the variability between models.

Multiple Model Comparison

The primary appeal of the Compare forecast feature is the ability to view multiple weather models side by side. Among the available models are ECMWF, GFS, Meteoblue, and ICON models. Having multiple models to compare allows for analyzing the level of agreement or disagreement between them, providing a sense of the range of possible outcomes. By comparing forecasts from multiple models, you can gain more confidence in predictions where the models agree and be more cautious where they don't.

Comprehensive Weather Information

The Compare Forecast feature covers various weather elements, including temperature, wind speed, and precipitation. The data format is identical to the Basic view in the detailed forecast, meaning these data points are presented visually and numerically, so you can understand the forecast intuitively.

Hi,
I'm from Brazil and I use most frequently the ECMWF model, due to its smaller area range (most accurate).
I frequently make a double check on the forecast (for same area and same period) using the GFS model
