How to hide a specific category posts in my monthly archive?

1. There are two ways of doing it:

   You can use a filter to alter the query when viewing an archive page. You will need to find the ID of your category ‘blogs’ (you can obtain it from the slug using get_term_by). Alternatively you can exclude a particular category by ID.

   add_action( 'pre_get_posts', 'my_change_query'); 
       function my_change_query($query){
           if(is_archive()){
              $blog_term = get_term_by('slug', 'blogs', 'category');
              $blog_term_id = $blog_term->term_id;
              $query->set('cat', $blog_term_id);//Include category with ID $blog_term_id
              //$query->set('cat','-'.$blog_term_id);//Exclude category with ID  $blog_term_id
           }  
        return $query
       };
   

   or, more commonly, you can alter the archive.php template file and insert the following just above the if(have_posts()).

   global $wp_query;
   $args = array_merge( $wp_query->query, array( 'category_name' => 'blogs' ) );
   query_posts( $args );
   

   See the Codex on query_posts and WP_Query.
