About the Valley

The Rio Grande Valley, is a four-county area with a larger population than South Dakota, Delaware, North Dakota, Vermont, Alaska, and Wyoming. With a land area of 11,122,712 square kilometers, the Rio Grande Valley is almost twice the size of Delaware and four times the size of Rhode Island.

The Rio Grande River forms the boundary between Texas and Mexico. The river, which starts in Colorado, enters the western end of the valley near the town of Roma and finishes the last 150 miles of its more than 1600-mile trek passing through the valley before it empties into the Gulf of Mexico at Brownsville.

The semi-tropical climate and irrigation water from the river and the many canals that are found throughout the valley help to make the Rio Grande Valley one of the major citrus and vegetable producing areas of the United States. It has also been listed as one of the top birding areas in the world with birders coming from around the world to see the many varieties of birds that are found here. The climate is semi-tropical with mild winters and hot summers. Day time temperatures that are normally in the upper 90's (Fahrenheit or 33 celsius) during the summer months can reach up to 110 degrees (44 celsius). The winters are mild and rarely go below 32 degrees (0 celsius). Most winter days are often in the 60-70 degree (1-21 celsius) range.
