Answer: Now is an excellent time to prune those hedges back. If they are very overgrown, you may want to reduce their size in 2-3 pruning sessions rather than all at once. To keep your shrubs healthy, the rule of thumb is to remove no more than one-third of the growth in any one pruning session. If you need to remove more than that, prune again in late summer or early fall.
Best wishes with your hedges!
