Jessica Alba certainly seems thankful for the sun down in Mexico ... heading out to the beach in another bikini and catching a few rays while on vacay with her family.
The actress was photographed Wednesday on a beach in Puerto Vallarta ... wearing just a tiny two-piece swimsuit and lying out on a beach chair.
She's got thick sunglasses and gold earrings on ... great for hanging out on the shore -- but, it doesn't look like Jessica planned on diving into the crisp blue water and splashing around.
She did dip a toe in ... walking out to the waves in a matching cover-up and huge sun hat -- and checking the temp alongside her husband Cash Warren and their 16-year-old daughter Honor.
Jessica -- ever the fashionista -- isn't wearing the same bikini we saw her in earlier this week BTW ... changing it up from the white and gray ensemble to one with a little bit of a darker hue.
Like we told you, it's a week of relaxation after a busy year for Jessica ... whose first feature-length film in five years dropped on Netflix back in June.
"Trigger Warning" didn't get particularly good reviews ... and, a week in Mexico might be just what Jessica needs to purge herself of all the negativity before the new year.
Thanksgiving just passed ... but, Jessica's giving a lot of fans a feast for the eyes!
