It never rains in LA—except when it does. It's common knowledge that the roads around here become insane when water falls from the sky, but it's special mom knowledge that the living rooms become insane, too. And speaking of insane, ever try planning a birthday party outdoors in January? Sure, you might have one of those gorgeous days Manhattan moms covet, or you might end up calling 25 kids and rescheduling. Either way—rainy day or birthday—you need to know where the indoor playgrounds are in LA and Orange County.

Note that many indoor playgrounds are open only for birthday parties on the weekends, not for drop-ins, so call before heading out. Several of the locations below also offer classes.

2. A Magic Forest

3. Noah's Ark at the Skirball
Actually an exhibit at the Skirball Cultural Center, Noah's Ark functions as a playspace.

4. Pamper & Play
Westside moms can choose between playing with their toddling little ones in the play area or taking advantage of supervised play as they sit upstairs and get some work done with the free Wifi. Either way, it's win-win.

5. Under the Sea
Under the Sea in West LA seems to be the last remaining location of this chain; the space offers plenty of room for kids to run and romp on a rainy day, with tables where Mom can make use of the free WiFi.

Wild slides, tunnels, and swings -- kids will definitely burn off any extra energy at this Anaheim playground (there's another location in Valencia, too).
