How extreme does Wewak's weather get?

The hottest, coldest, wettest and snowiest days Wewak has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 28 years of daily weather observations (1997–present), from the Wewak Intl station 6 km away. Updated through July 2025 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

Methodology & sources

Temperature & precipitation — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.
