Climate statistics for Australian locations

Monthly climate statistics

All years of record

Temperature | Rainfall | Other daily elements | 9am conditions | 3pm conditions

NORTHAM

An extended list of climate statistics recorded is provided below. There is also a summary table for printing with the commonly requested statistics and a map showing the location of this site. Monthly statistics are only included if there are more than 10 years of suitable data.

Note: Many statistics are updated quarterly and recent weather events may not be represented in the statistics below. For more current information on recent extreme values, please refer to the corresponding Daily rainfall, Maximum temperature and Minimum temperature data tables for this site, and our Australian Climate and Weather Extremes Monitoring System. Missing observations associated with the observer being unavailable (where observations are undertaken manually), a failure in the observing equipment, or when an event has produced suspect data may result in an extreme event not being recorded.
