Coastal Lowlands (Georgetown, East Coast Demerara, New Amsterdam)
December is humid with alternating bright, hot days and sudden tropical showers; holiday travel picks up and coastal towns become busier as locals travel to family and beaches. The sea breeze moderates daytime heat, but evenings stay sticky and mosquitoes are active - pack repellant and lightweight long sleeves. For visitors this month is convenient for combining city museums with short boat trips, but book ahead for popular weekend getaways along the coast.
Lower Essequibo & Interior Lowlands (Bartica, Vreed-en-Hoop, Essequibo River islands)
December alternates between humid air and brief tropical downpours with river levels steady to rising, depending on lingering late-season rains. The Essequibo estuary is busy with local movement and weekend visitors from Georgetown; book transport early for holiday travel. For visitors, this is still a workable month for lodges and river trips if you plan for sudden squalls and protect electronics and luggage against splashes.
Central Rainforest & Protected Reserves (Iwokrama, Kaieteur region approaches, protected forests)
December alternates between hot, muggy mornings and heavy tropical showers; the rainforest feels alive and thick with the season’s growth and insect chorus. Lodge stays can still be comfortable but plan for wet transfers and possible last-minute schedule changes for flights or boat legs. For travelers seeking dramatic waterfalls and dense jungle ambience, this month can be rewarding if you are flexible and well-equipped for wet weather.
Rupununi Savannah (Lethem, Annai, South Rupununi)
December is wet and lush with warm, humid days and regular afternoon thunderstorms that refill ponds and small rivers, rejuvenating the savannah ecology. Tourist activity reduces compared with the dry months, but the scenery is dramatic and river-based movement picks up; travellers should expect some road closures and to prefer boat or air connections. For photographers and birders who tolerate humidity, the season is excellent; bring rain gear and waterproof storage for electronics.
Pakaraima Mountains & Kaieteur Plateau (Kaieteur Falls, Mount Roraima approaches, western highlands)
December alternates between warm clear spells and heavy mountain showers, with Kaieteur among the most dramatic displays when the falls benefit from recent rains. Holiday travel increases slightly, but many serious treks are still best postponed until slightly drier windows; shorter day-trips to view the Falls remain possible when flights operate. Travelers should pack waterproof layers, expect cool plateau breezes, and allow extra time for air or ground transfers.
