Travel time: Year-round
Campeche operates under a tropical savanna climate, categorized by distinct wet and dry periods. Unlike temperate zones, the city’s weather is governed more by moisture levels and shifts in wind than by dramatic changes in temperature. It is consistently hot, with average highs ranging from 81°F (27°C) in January to 97°F (36°C) at its peak in May.
The day typically starts with high humidity and clear skies. By mid-morning, the heat intensifies rapidly, often accompanied by a light sea breeze from the Gulf of Mexico that provides slight relief to the coastal areas but does little to penetrate the inland city streets. In the rainy season (June to October), late afternoons frequently bring sudden, heavy convective thunderstorms. These tropical downpours are intense but often brief, clearing the air and providing a temporary drop in temperature before the humidity returns for the evening.
This is the most intense period of the year. May is the hottest month, with temperatures frequently exceeding 100°F (38°C). During these months, the air is paradoxically drier than in the summer, but the sheer thermal intensity can feel oppressive. "La canícula"—the late spring heat—is a significant part of the local experience, when the sun is at its zenith.
While the temperatures dip slightly from the peak of May, the humidity surges, making the air feel much heavier. September is historically the wettest month. This season also coincides with the Atlantic hurricane season; being situated on the Bay of Campeche, the city is prone to tropical depressions and cycles of heavy rain that can last for several days.
This is the most temperate time of year. Rainfall decreases significantly, and the humidity becomes more manageable. In January, the coolest month, daytime highs stay around a pleasant 81°F (27°C). The skies are primarily clear, and the wind speeds are slightly higher, making it the most comfortable time for outdoor exploration.
A unique aspect of Campeche’s climate is the Norte. Between November and March, cold fronts from the north (often originating in the United States and Canada) sweep across the Gulf of Mexico. These "Nortes" bring a sudden drop in temperature, gray skies, and strong, gusty winds that can reach over 40 mph. For locals, a Norte is a celebrated break from the usual heat, though it can cause rough seas and coastal flooding near the Malecón (seafront).
In Campeche, the thermometer rarely tells the whole story. The heat index—the "real feel"—is almost always higher than the actual temperature due to the proximity to the Gulf. In the summer, an 85°F (29°C) day can feel like 95°F (35°C) because the high dew point prevents sweat from evaporating efficiently. Conversely, during a winter Norte, the damp wind can make 65°F (18°C) feel surprisingly chilly, prompting locals to don light jackets and sweaters.
The historic center of Campeche, a UNESCO World Heritage site, was designed with the climate in mind. High ceilings, thick limestone walls, and large windows were intentional architectural choices to facilitate airflow and keep interiors cool. Locals typically adapt by scheduling heavy activity for the early morning or after sunset, observing a traditional midday lull when the sun is at its most punishing.
