Weather in Hobart in May
Australia · 20-year averages, May
Shoulder season. May is shoulder season in Hobart — cheaper, quieter, and a genuine gamble. Highs sit at 14.3 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.
May ranks 8 of 12 in Hobart: past the worst of the year but short of January, which is the month to book if the dates are open.
Rain on 12 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 14.3 °C the difference between a good day and a miserable one is entirely down to what you are wearing.
What the averages hide
Averages flatten a month, and this one hides a few things: the day barely swings — 5.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest May day reached 22.8 °C and the coldest night fell to 4.1 °C, and the wettest single day dropped 29 mm — roughly 53% of the month's rain in one day.
May is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest May on record still delivered 132 mm against 21 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 55 mm average is a reasonable planning figure, not a promise.
Wind is light at 14.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, which at 14.3 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.
How May sits in the year
The month is on the way down: 2.9 °C cooler than April, with June dropping another 1.8 °C. The first week and the last are not the same trip.
Daylight in May
9.7 hours of daylight, losing 1 hours across the month. That is between Hobart's extremes of 15.3 and 9 hours, so days are long enough not to constrain the plan.
Sea temperature
The sea sits at about 14.4 °C in May — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. The sea peaks at 16.6 °C in February and bottoms out at 12.4 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.
How busy it gets
Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
May in Hobart versus nearby
If Hobart is one option among several, the nearby comparison is worth making. Launceston is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Devonport is close enough to be a coin toss — within a degree on temperature, 1 day less rain.
So: May is a compromise. January is 25 points better and is what Hobart is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
