Light is not affected by wind. You're not seeing visible light, but the thermal emissions have the same properties. Think of an electric burner on your stove. At some point it gets so hot that it emits visible light (the dull cherry red glow you see). When it's not quite that hot, it's still emitting radiation but it's not in a visible range. It's not 'heat' per se, you can't feel it, but rather it is a form of electromagnetic radiation with properties very similar to visible light but having a longer wavelength.
You can never have too much ammo — unless you're swimming.
