In Final Fantasy XI, the weather (and day of the week, which are all named after elements) does affect spell resist rates, as well as crafting success rates. Thunder-based spells cast during lightning storms will more often land for full damage; crafting an item using a Fire Crystal on Watersday (and/or during rainy weather) will more likely result in critical failure, causing you to lose some or all of your ingredients.
