Question on checking M/Taf and cloud ceiling

I fly at the beach that can have a pretty heavy marine layer in the AM. When I check M/Tafs for the airports around my spot there’s one 4.5 miles south, 12 miles north and 3 miles east. The East one isn’t reliable because it’s usually different climate than from the coast. Then the southern one can vary from my spot as well. Sometimes I’ll check the south airport and it will be covered in 500ft layer but my spot is broken sky with plenty of room to fly. Is there an app for checking cloud ceiling in your vicinity? What would u recommend?
