May weather forecast
American Samoa, USA

May ushers in a notable shift in American Samoa's climate. As the islands transition more deeply into the dry season, the reduction in rainfall becomes more pronounced. Temperatures during May remain comfortably tropical, typically ranging from 78°F (25.6°C) to 87°F (30.6°C). While the humidity starts to relent slightly, it's still palpable, providing a sense of warmth that's intrinsic to these Pacific islands.

The transition from April to May sees a more pronounced reduction in precipitation, offering drier days and less frequent rain events. This trend signifies the islands' move further away from the wet season, preparing for the drier months that lay ahead.

Pago, due to its geographical disposition near mountainous terrains, continues to witness a relatively higher amount of rainfall compared to other regions of American Samoa. This localized weather phenomenon, attributed to the orographic effect, emphasizes the diverse microclimates that exist within this compact territory.

By the time May rolls in, the threat of tropical cyclones becomes minimal, making it a favorable period for tourists to explore both the terrestrial and marine wonders of the region. The clearer waters of May, with diminished runoff from the rains, become particularly inviting for divers and snorkelers. This period offers a window into American Samoa's vibrant marine life, with enhanced visibility revealing the intricate tapestry of coral reefs, fish, and other aquatic inhabitants.
