Does Sunny Day Affect Flare Blitz?

Question

I was reading on Smogon the other day that Sunny Day affected moves like Flare Blitz, although it didn't specify why (I assumed it had something to do with power). I looked up both moves on Bulbapedia, and I didn't see anything there, so can anyone confirm that in the 6th gen Sunny Day affects anything other than pokemon who have Growth (+ATK/SPA)?

Answer 1

Sunny Day causes the weather effect of intense sunlight which alters the way some things work for a few turns:

• Increases the power of Fire-type moves by 50%.
• Decreases the power of Water-type moves by 50%.
• Allows Solar Beam to be used instantly.
• From Generation V onward, causes Growth to raise Attack and Special Attack two stages each.
• Activates the following Abilities: Chlorophyll, Dry Skin, Flower Gift, Forecast, Leaf Guard, Solar Power.
  • Causes Forecast to change Castform to its Sunny Form.
  • In Generation V onward, causes Flower Gift to change Cherrim to its Sunshine Form.
• In Generation IV, changes Cherrim to its Sunshine Form.
• Guarantees Harvest will restore a held Berry.
• Changes Weather Ball to a Fire-type move and doubles its power.
• Prevents Pokémon from becoming frozen.
• Causes Moonlight, Synthesis, and Morning Sun to recover ⅔ of max HP (twice the normal amount in Generation II).
• Lowers accuracy of Thunder and Hurricane to 50%.

As Flare Blitz is a fire typed move, its power is increased by 50% by the effects of Sunny Day.

Answer 2

Yes. Sunny Day increases the damage of fire-type moves by 50%. Since Flare Blitz is a fire-type move, it is also affected by Sunny Day.

To expand the answer, I'll list effects of Sunny Day which i know below:

• It increases the damage of fire-type moves by 50%
• It lowers the damage of water-type moves by 50%
• Thunder and Hurricane have 50% accuracy instead of 70%
• Moonlight, Synthesis and Morning Sun heal 66.7% instead of 50%
• Solar Beam doesn't have to charge and is used immediately
• Growth increases both stats by 2, instead of only 1.
