The weather forecast data are provided by the DarkSky service. Same as the meteorologist on the TV may be wrong, this service might be wrong, too. But, if the forecast is always incorrect, please check if the fishing place is correct ( it can happen that the name of the fishing place is the same, but the country is different) or contact our customer support [email protected]. An incorrect weather forecast has a great impact on our calculations. Restrictions on air traffic during the pandemic have a negative impact on the accuracy of weather forecasts.
