In contrast, the Andean highlands, encompassing cities like Cusco and Arequipa, continue to receive significant rainfall, although it begins to decrease compared to the peak wet months of January and February. Average precipitation levels drop to 120mm (4.72"). Daytime temperatures generally fluctuate between 10°C (50°F) and 18°C (64.4°F), with colder temperatures close to freezing at higher altitudes during the night.

Over in the Amazon rainforest, March remains a wet month for cities like Iquitos and Puerto Maldonado, although precipitation begins to subside slightly. Rainfall levels can still reach around 280mm (11.02"), while temperatures typically stay above 30°C (86°F), continuing to provide a hot and humid climate.

In comparison to February, March sees a slight decrease in temperatures on the coast and a reduction in rainfall in the Andean and Amazon regions. Looking ahead to April, all three regions anticipate further reduction in precipitation and a continued decrease in coastal temperatures.
