Thanks to its location in the Gulf of Mexico, Houston has a reputation for being hot and humid, with intermittent and (often unexpected) bursts of rain. If you’re dreaming of sun-soaked festivals and beach parties, the high season stretches from June to September, but be prepared to sweat your way through your stay. If you’re keen to avoid the blistering heat, aim for the shoulder season from March to May and October to November. If you’re keen to avoid the crowds, aim for the low season from December to February, but be prepared for cold.
