Genuinely Hot, Humid Summers

Lafayette's summers run real and genuinely hot and humid: an average July high near 90°F, with relative humidity peaking around 75.84% that same month. This record states Lafayette's summer heat and humidity plainly rather than softening it into a generic 'warm and sunny' pitch.

Short, Mild Winters -- No Snow or Ice in a Typical Year

Winters in Lafayette run genuinely mild: an average January low near 44.2°F, with no snow or ice in a typical winter -- a real, positive draw for movers from colder climates, though summer heat and humidity are the real trade-off.

Wet and Partly Cloudy Year-Round

Lafayette stays genuinely wet and partly cloudy for a large share of the year, even in its comparatively drier month (October, at approximately 64.71% average humidity, the year's lowest) -- movers should expect real, frequent rainfall rather than a dry southern climate.

The Vermilion River Adds a Genuine Local Weather Dimension

As detailed on the flood-hurricane-risk topic page, Lafayette's own Vermilion River geography means heavy-rainfall events carry a real, documented local flood risk history -- a genuine climate-adjacent consideration alongside routine seasonal temperature and humidity patterns.
