The climate of Harlingen (Texas
- United States of America)
Harlingen is a medium sized city located in the southeastern part of
the state of Texas in Cameron County. According to several sources the
city was named after the Frisian city of Harlingen, the Netherlands.
The city is located in the vicinity of the Gulf of Mexico in the Rio
Grande Valley. The city was founded at the beginning of the 19th
century on the banks of the Arroyo Colorado River. Just outside the
city the Port of Harlingen can be found. This port is located on the
Gulf Intracoastal Waterway which was especially dug for ships that are
unable to navigate through the Gulf of Mexico. Harlingen is supplied
via Valley International Airport. Harlingen has a warm maritime
climate strongly influenced by the Gulf of Mexico. Because of this
winters are much warmer here than in the interior of Texas. Longer
periods with subzero temperatures (during the night) are uncommon.
Other than in most cities in Texas most precipitation can be recorded
during the end of summer. During the warmest days of summer
temperatures may easily rise up to 40 degrees Celsius (104 degrees
Fahrenheit).

More climate information
Climate figures are very useful but don’t present a general impression
of the climate and the eventual weather circumstances within a certain
period. The figures don’t always reflect the chance of wintry weather,
extreme heat or hurricanes. That is why we offer useful extra climate
information for each month of the year:
