%X In the present work, we perform an empirical model of the geomagnetic field quiet daily variation from the years 2010 to 2019 in Cachoeira Paulista (22.7oS, 45.0oW). We obtained the magnetic field data from the Brazilian Space Weather Program, called Embrace MagNet. Thus, we constructed a model to calculate the quiet daily variations of the geomagnetic field for each month in terms of the solar cycle, day of the year, and local time. The simulations have been compared with the observational data to validate this model in a low latitude station. The results show some discrepancies in some hours, but in most hours, we have a good agreement with the simulations and observational data. The model represents a high accuracy of the daily variation of the geomagnetic field, in which the correlation was 0.96. Thus, this model could be a potential tool for monitoring the geomagnetic field for space weather predictions.
