Sevilla in January is heaven, especially if you are from NYS. Isn't the poster of this topic from Buffalo? If that is correct then Sevilla will seem like heaven in January. (I
am from central NYS and drive through Buffalo almost weekly on route to Niagara.)

Once, I went to Sevilla in February (1997) and one from my group insisted that we stay at a hotel that had central heating. We lucked out and never needed it.

I am going to Madrid in February 2001 and might go to Sevilla, but only if the Madrid weather is wet and cold.
