Understanding the Compare Forecast Feature in Windy.com
-
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.
Giveaway
We are also launching a seasonal giveaway. The theme of this competition is WEATHER MODELS! We want to know what is your most used weather model. Comment your answer below this article until 30.6. and we will select 3 users who will win our significant Windy snapback.

@Korina I use the UKV model as it seems to suit my location best.
-
In Southern-Germany i often use ICON-D2 Meteogram for Sailing :)
-
In Colombia I use the ICON model

@Korina
Over the past years, the Canadian GEM model has been the best for me, especially in the cold half of the year. But now I don't have access to it. -
To be perfectly honest ... all models are fantastic.. .the most I do use is the live weather radar especialy with live lightning.. thanks again for such a magic windy app.. what would be nice is aviation overlays : similar to this link https://upload.wikimedia.org/wikipedia/commons/d/df/Aviation_weather_forecast_chart.png -
I used the basic model most of the time. I used it for the area where I live.
-
Thanks for your great app. To keep it short: I use a combination of ECMWF and Icon-D2 . Do ypou think you could add a CIN, LFC and SRH to the Maps? :)
-
For a general overview I mostly use the comparison feature. For a more detailed check whether the conditions are good enough for paragliding I check the airgrams of each available model separately. Most of the time ICON-D2 seems to be the most accurate for the region around Salzburg.
-
For Madeira Island, ECMWF is probably the best. ICON sometimes exagerates a bit in rain events. GFS barely "sees" the island due its lower resolution. I am responsible for operations in Madeira's eletrical grid, i use Windy forecast data as an input for risk evaluation/decision.

El modelo que tiene mayor acertividad para muchas regiones de Venezuela es el Europero, aunque para los productores se les entrega el comparativo de modelos entre el Americano, Europeo y Aleman.

@Korina - Just joined -- but so far ECMWF is working best when i compare

@Korina As someone who loves to sail and explore the Gulf of Mexico, I rely on the HRRR weather model for accurate and timely updates. It helps me make informed decisions and ensures my voyages are safe and successful. I also compare forecasts from the GFS and ECMWF models to gain a deeper understanding of future weather conditions. Windy provides a powerful platform to help me harness the full potential of weather models. I'm grateful for this remarkable tool and look forward to continuing my weather adventures with its assistance.

My favorite ist the ECMWF, works well for Cologne, Germany where I live
-
In Colorado, I use the ECMWF for general trends for the coming days, and HRRR for getting an idea for hourly conditions for the next 8-12 hours in specific locations since the mountains can cause drastically different weather 50 miles apart.
-
I use the ECMWF most of the time, but when I want to be more confident about the weather I check the compare tab.
-
I believe the CAPE index is a new interesting feature:
-
I usually rely on the ECMWF models in California, USA. They've been very good for desert and foothill camping planning.
-
Weather Radar of course, as Windy.com combines weather models (rain & forecasts), and it's always only minutes from it's next update.
-
The ECMWF 9km model has been the most reliable model for me here in NZ
