Guyana in March: Weather, Crowds & What to Expect

Coastal Lowlands (Georgetown, East Coast Demerara, New Amsterdam)

March often brings the clearest skies of the first half-year along the coast; humid heat becomes noticeable in the afternoons, with highs nudging 30-31°C. The sea breeze keeps beaches like Kitty and the East Coast attractions usable; you’ll find fewer mosquitoes than in heavier-rain months, and boat trips to the mangroves are generally on schedule. This is a good time to arrange transfers inland before the main rains; lightweight long sleeves for sun and insect protection are handy after sundown.

Lower Essequibo & Interior Lowlands (Bartica, Vreed-en-Hoop, Essequibo River islands)

March sees afternoons warming and humidity increasing, and the river channels begin to warm as well, attracting more birdlife and prompting early fishing activity. Sandbars around Bartica and the lower Essequibo make for attractive day-trips; interior trails are drier and easier to hike. Travelers should pack light, breathable clothing and a sun hat - it’s an efficient month for moving upriver and arranging charters into forest reserves.

Central Rainforest & Protected Reserves (Iwokrama, Kaieteur region approaches, protected forests)

March brings increasing humidity and the first thunderheads building above the forest; mornings remain excellent for birding, but afternoon storms start to become more common. Streams still run clear enough for canoeing and some smaller waterfalls are accessible without strenuous detours. Visitors should plan activities in the early day, pack waterproof clothing, and expect the forest paths to get sticky underfoot as ground moisture increases.

Rupununi Savannah (Lethem, Annai, South Rupununi)

March marks the start of the drying trend in the Rupununi - water levels slowly retreat and early tracks begin to reappear, while afternoons warm considerably. Camping and overland safaris become more plausible again and horses return to more traditional grazing grounds; this is a transitional period when both wetland and dryland species are visible. For visitors, it’s wise to keep a blend of wet-and-dry gear handy and to book local transport close to travel dates.

Pakaraima Mountains & Kaieteur Plateau (Kaieteur Falls, Mount Roraima approaches, western highlands)

March sees increasing humidity and more unstable afternoons as thunderclouds build from the interior uplands; Kaieteur’s flow remains dramatic and surrounding trails can begin to thicken with mud. Mountain top nights remain pleasantly cool compared with the lowlands, but expect wet footprints on approach trails and supply flights to be weather-dependent. Travelers should schedule buffer days for any mountain excursions and bring waterproof footwear and a warm layer for summit breezes.
