What the Adelaide climate table shows

Values are multi-decadal climatological averages for the -34.9287, 138.5986 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.

Frequently asked questions

Is Adelaide climate data a forecast?

No. These are multi-decadal averages for the grid cell, not a prediction for any particular year.

Why do the numbers differ from a weather app?

An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
