Brownsville has a subtropical climate just outside of a humid semi-arid climate. The nearby waters of the Gulf of Mexico help keep Brownsville cooler during the summer relative to cities further inland such as Laredo and McAllen. Thus temperatures above 100 °F (37.8 °C) are uncommon, with an average of only 1.1 days reaching that level of heat.
