Forecast

Geismar's weather is often humid and hot, with air pressure changing throughout the year. The air pressure is affected by the Gulf of Mexico's moisture and the Mississippi River's cooling effect.

Geismar's low elevation near the coast and river makes it prone to changing air pressure, with winds blowing in from the Gulf and pushing air up and down.

In summer, hot air rises, making air pressure low, and thunderstorms form. In winter, cold air sinks, making air pressure high, and skies are clear.

Geismar has a humid subtropical climate, with air pressure influenced by the ocean's warmth and the river's cooling. This mix creates frequent weather changes and storms.
