In order to understand the patterns and intensities of the Surface Urban Heat Islands (SUHIs) of Santiago emission temperatures were calculated using 53 Terra MODIS satellite images and then factor reduction was performed using Principal Components Analysis (PCA). In addition, intensity maps of SUHIs were created. Results show that the maximum temperature (with intensities measuring above 5°C) within the SUHI tends to be located in the central municipalities of Santiago, as well as in the municipalities of Huechuraba and Quilicura. Furthermore, PCA reveals four typical patterns, which explain 90.6% of cases: consolidated SUHI, piedmont SUHI and high income wedge, no SUHI and high intensity SUHI in the south. It has been hypothesized that the lack of a SUHI to the drain effect, which is linked to the katabatic breeze, causing the SUHI to move toward the west sector of the cityCon el objetivo de conocer los patrones e intensidades de la Isla de Calor Urbana de Superficie (ICUs) de Santiago se han calculado las temperaturas de emisión para 53 imágenes Terra MODIS, se han trazado mapas de intensidad de la ICUS y se ha aplicado Análisis de Componentes Principales. Los resultados muestran que la ICUs tiende a localizar el máximo en las comunas centrales y de Huechuraba y Quilicura, con intensidades superiores a 5°C. El ACP revela cuatro patrones típicos, que explican el 90,6% de las situaciones, a saber: ICUs consolidada, ICUs del piedmont y cuña de altos ingresos, un tipo sin ICUs y otra más intensa al sur. De las situaciones sin isla de calor, se ha sugerido la hipótesis de efecto sumidero, asociado a brisa catabática, que barre la ICUs y la desplaza al poniente de la ciudad
