What is the barometric pressure in Ciudad Madero today?
The live reading at the top of this page is the latest sea-level pressure reported by Tampico/Mina Intl (MMTM), 5 km (3 mi) from the city center. It updates about every 10 minutes; the graph shows the last 24 hours.
What is normal barometric pressure in Ciudad Madero?
