Climate
Under the Köppen climate classification, the climate of the Challenger Islands is classified as a tropical rainforest climate (Af) that borders on a humid subtropical climate. The lowest temperatures are recorded in July and August (minimum 15 °C or 59 °F) and the highest in February (maximum temperature 28 °C or 82 °F[56]), the summer season in the southern hemisphere. Winters are relatively mild. The rainiest month is May, though the island experiences year-round rainfall. The islands' isolated location exposes it to winds which help to keep the temperature fairly cool. Precipitation averages 1,118 millimetres or 44 inches per year. Occasionally, heavy rainfall and rainstorms strike the island. These occur mostly in the winter months (June–August). Since it is close to the South Pacific High and outside the range of the intertropical convergence zone, cyclones and hurricanes do not occur around the Challenger Islands. There is significant temperature moderation due to its isolated position in the middle of the ocean.
