Not to place the candles in a windy area:
One is to avoid placing the candles in a windy area, as the wind can extinguish the flame. [If the candles were lit in an area where there is wind, and the wind extinguished the candle prior to its remaining lit for a half hour, then one must relight the candles. The candles are to be relit without a blessing.]
Must one who lights outside place the Menorah in a glass box in order to protect it from the wind?

Other opinions: Some Poskim rule the candles are to be relit with a blessing. [Peri Chadash 672:2]
The reason a blessing is not recited: As we hold that the initial lighting does the Mitzvah, and it is not for certain that the wind will extinguish the candle at the time of the lighting. [Shaar Hatziyon 673:30 in name of Peri Megadim; See Taz ibid; Kneses Hagedola ibid]

 Sheilas Yaavetz 149 writes that one should do so. See Shut Leiv Chaim 3:147 [Rav Chaim Falagi] with regards to why one is not required to actually see the candles without the medium of a glass.
 Birkeiy Yosef 673:8 writes that this is not the custom. The Nimukeiy Orach Chaim asks why in truth this is not required from the letter of the law, being that without a casing the wind is liable to blow out the candles, and one must light the candles in a way that they could now last for a half an hour. Nevertheless he concludes that if it were required then all the Poskim would not have omitted this detail. See there!
