The long-range weather forecast for the Comic-Con International (July 23-26) calls for Mostly Sunny during the days with highs around 72°. Evenings, it'll be Partly Cloudy and get all the way down to 66° – 68°.
And for those of you who still think the con should move to Las Vegas, the forecast for that town for those dates calls for highs around 110°, lows around 86° and unusually high (for Vegas) humidity. Still wanna go there?
