RN Climate
Semi-arid climate, because of erratic rains and high temperatures all year round.
The average monthly temperatures range between 26 and 28 C, with a minimum of
21.1 C in August and the maximum around 34 C, from September to November.There are two seasons: a dry and a rainy season, the largest amount of rain
between February to May, also with higher relative humidity, averaging 78% to 61%.

In the coastal environment of RN predominate beaches with Beachrocks, cliffs, dunes,
restingas, estuaries, mangroves, lagoons and groundwater ponds.
The largest areas of mangroves and apicuns of the region are found in the mouths of
rivers Apodi-Mossor (Areia Branca / RN) and Piranhas-Au (Macau / RN).

In relation to the biota of the region, in the mangroves, the mangrove crab, the mullet and the
blue land crab are predominant. In the marine environment, fish diversity is quite high and
species are found such as sardines, Vermillion snapper, Yellowtail snapper, Salminus, albacore
(or tuna) and flying fish, as well as rays and sharks. There is also the presence of crustaceans
(lobsters and shrimps) and mollusks (octopus).

We can also highlight the presence of cetaceans (whales, porpoises and dolphins), the most
common being the sotalia, the tucuxi dolphin and rough-toothed dolphin and mammals like the
manatee.

Regarding chelonians, according to the Center for Sea Turtles/ IBAMA, the coastal area
between Guamar / RN and Icapu / CE can be taken as a reproduction area of somespecies of turtles in the period from September to April.
The birds use the estuarine areas of the region to nest. Collared plovers, grey-headed gull
and Brown Noddy occur in the region.
CONSERVATION UNITS
The Conservation Unit closest to the activity is the State
Sustainable Development Reserve of Ponta do Tubaro in Guamar
and Macau, Rio Grande do Norte.

In fishing the main interference of the oil activity, are excluded areas of production
platforms and vessel traffic in support of E&P activity. However, these interferences
generate a insignificant impact on fishing activity, considering the great fishing area used by
the artisanal fleet.
