What to expectPlumbon through the year

Plumbon changes little through the year. Average daily highs stay between 31 and 32 °C, so no month stands out as a season in the way it would further from the equator.

Counted across a normal year, 365 days a year reach 25 °C, 148 of them reach 30 °C. The warmest reading in the 1991–2020 record is 38 °C, in October.

Rain is strongly seasonal. December averages 362 mm against 13 mm in August — 28 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Plumbon is warmest in May at 30 °C and coldest in August at 28 °C. Sea temperature lags the air by a month or two, which is why late summer swims warmer than early summer at the same air temperature.
