Barranquilla weather in December

Regulars are specific this marks the start of the region's dry season, hot and sunny weather becoming the norm, though the sea itself tends to turn genuinely rough by afternoon even on an otherwise calm-looking day, calmest early in the morning. Our row backs that hot, still-humid read, 32.1C reading as a brutal 38C, over 24.6C nights, with 31.3mm of rain across 8.3 days and humidity at 82 percent. Regulars are consistent this counts as genuine high season locally, with Colombians themselves traveling for the holidays, driving up prices and traffic noticeably beyond the rest of the year. The sea sits at a warm 29.4C for anyone timing a swim around the calmer morning hours. The record: 10.3 hours of sun, a 20.8 kph wind and AQI 46.

Forum posters describe the Caribbean coast around Barranquilla as staying roughly 28-32C year-round, hot but not overly humid, and consistently name July and August among Colombia's driest months - a generalization that actually reflects the interior highlands around Bogota more than this coast, since Barranquilla's own real dry season runs January through March, well before July, and July itself sits closer to the middle of the coast's wetter mid-year stretch. Posters note forecasts often predict rain that in practice turns out to be just a few minutes of tropical shower. Posters are direct that Barranquilla itself has no real beach, with the waters made turbid by the nearby Río Magdalena emptying into the sea, and generally point visitors toward Santa Marta or Cartagena instead for beach time. Posters generally rate July as a warm, comparatively dry time to visit the Barranquilla area, with beach logistics rather than weather the main planning consideration.

Forum posters place January solidly in Colombia's dry season on the Caribbean coast - mild, tropical, essentially the same climate pattern as any Caribbean island, with the wet season not returning until May through November. Barranquilla can flood during heavy rain spells, so the dry season carries a real practical upside beyond just comfort. Posters are candid that the city isn't typically thought of as a tourist draw outside of Carnival (held in February) - it's valued more by visitors looking for an authentic, less-touristed alternative to nearby Cartagena or Santa Marta, with the Malecon riverside walk cited as a worthwhile if quieter stop.
