Chilli has it absolutely right.
Understand the difference between "legal" and "safe". "Legal" is in sight of the surface, and you can satisfy that by peering down through a tiny hole.
"Safe" will vary depending on your experience and training, and the aircraft's equipment. You have to consider a) how you will navigate, b) whether you will still be legal 10nm further on, and c) how you wil get back down underneath the clouds.
(Another example of "legal" but not "safe" would be flying cross-country in 3km viz. I have flown in this kind of viz several times, flying IFR and navigating using navaids, but I've attempted (just for fun) to fix my position visually, and it's pretty difficult. Not impossible if you use the correct techniques, but not something to try by yourself for the first time.)
