Everything below is collected in one spot so you do not have to cross-check Geelong climate: monthly averages by hand. The gap between Jul and Jan is 10.9 C here: 9.1 C against 20.0 C. No month dominates: the wettest is Nov at 2.08 mm/day, the driest Mar at 1.17 mm/day. Taken together that is roughly 598 mm of rain a year for the grid cell. Values come from a public open API; a successful result is cached so a later outage never blanks the page. The table underneath carries the per-month breakdown; the related pages cover the same dataset nearby.

What the Geelong climate table shows
Values are multi-decadal climatological averages for the -38.14711, 144.36069 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
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.
How much rain is 2.08 mm/day in a month?
Rain is recorded as a daily mean, so 2.08 mm/day is roughly 63 mm across a 30-day month.
