Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Let me first say that most of the inspiration to this build goes to pete101011 and his Janna build.
Janna, the Storm's Fury
Teleport - A good spell for Janna. Although her Passives make her super fast already, it's always better to Teleport.
Clarity - NEEDED. Whether you're trying to hold against a Ryze in your lane early game, running from a gank mid game, or need to refill some mana bars in a teamfight late game. You'll likely use this on recharge if you're actively doing something.
Howling Gale - Your trademark skill. The skill that'll have people ragequit. You can use this skill as a quick, long range disable. Just Q-click-Q, and you can catch up to use Zephyr and your Deathfire's Grasp for massive damage. However, it's true power lies in farming. When pushing a lane, use as directed.
Step 1: Try to cast just before a new wave of minions arrives. Use your own minion wave on the minimap as reference to their position.
Step 2: Aim for the middle of the lane. You may angle it to attempt to hit opposing lane champion(s).
Step 3: ???
Step 4: PROFIT!
Zephyr - Also an amazing skill. Passive speed boost, Active slow and damage. It becomes quite spammable later on.
Eye of the Storm - While Howling Gale pushes your lane, this skill lets you keep it. Having trouble against the annoying Urgot who spams his Acid Missiles at you every chance he gets? Pop this on yourself and fire a Gale/Zephyr back. Holding a near-dead tower against seven waves of minions that somehow congested? Pop this on your tower, then farm like a boss.
Monsoon - Your insurance skill. Use it when your EotS is on recharge and you're under severe pressure. Knock foes back and heal, then run. Useful tool in team battles that aren't going in your team's favor.
Deathfire's Grasp - AP, mana regen, cooldown reduction. This alone would make the item desirable. But it also comes with a great damage spell. :D
Archangel's Staff - Helps manage mana, and comes with a good AP bonus.
Zhonya's Ring - A TON of AP. And comes with an insurance effect.
Rhylai's Crystal Scepter - Health, AP, and gives all your spells a slow effect. Nifty.
Frozen Heart - If the opposing team has a lot of physical DPS.
Aegis of the Legion - If you wish to play a more support role.
Void Staff - For moar damages. Can replace your boots. Your Passives can make up for the lack of them.
Although you have massive AP, don't think you can do high burst damage like a Ryze or Annie. Janna is a lane-pushing caster. Push lanes. That is your job from early to late game. And once you've pushed lanes all the way back to the opposing Nexus, act more like a support champion, rather than a burst DPS champion. Eye of the Storm pressured allies, Howling Gale escaping enemies, Zephyr dangerous DPS champions, and Monsoon if an Alistar or Sion get too close to your fleeing team.
Since your job is to kill waves of minions and push towers, preferably take middle lane in the beginning. However, if there's a stubborn Vlad or Morgana on your team who won't leave mid, just take another lane. No biggy. Make sure to push your lane as much as possible. Ignore all else, as pete101011 said. At least take out one tower before moving to another lane to help. Do this and your team will win, even if you have a 20 kill deficit against the opposing team.
That's pretty much all you need to know to manage an AP Janna. This is my very first build, so go easy on the critiques. If you have any suggestions to improve this, please mention them. Thanks!
