Brisbane in May
What to expect
In Brisbane, May sits in late autumn, a shoulder-season month where the feel can shift as the season turns. Most days feel warm without being relentless, with evenings that ease back comfortably. Daylight is moderate, so steady pacing works well. Comfort is usually predictable, so a standard day plan works well. A practical way to frame the month is that moist air can add weight to longer walking days, while intermittent wet spells can nudge plans around.
