Residents and visitors flocked to the beaches of Galveston, Texas, to get a glimpse of something they don't expect to see this time of year: clear, blue ocean water.

Memorial Day Weekend is generally a popular holiday for the beach, but visitors here usually see brown, murky water. In late May, runoff from the rivers that drain along the Galveston coast is almost always muddy. But a change of direction in ocean currents temporarily pushed clearer water from the Gulf of Mexico toward the coast over the weekend, the National Weather Service said.

Some theorized that the current change might have been impacted by Subtropical Storm Alberto , but the National Weather Service said that's highly unlikely since the current came from the southwest.

This gave beachgoers a few days of pristine water, and images were shared by Texans on social media.

"Whether it's true or not may be a trending debate on social media, but those of us who call this Island home know that these last few days have been incredible ," the city posted on Facebook.

The water was so blue, some locals said in social media posts that the city must have put blue dye in the ocean ahead of the holiday, the Houston Chronicle reported.

However, as expected, the beautiful water was only temporary, and on Wednesday, the murky water returned to the coastline , according to KPRC-TV. The sediment's return is beneficial to many non-human creatures, so marine biologists were pleased to see its return.

"It feeds the shrimp and the fish and the oysters ," marine biologist and Texas A&M-Galveston professor Dr. Tom Linton told KHOU.com. "So, we marine biologists love that dark water."
