Weather in Launceston in May

Shoulder season. May is shoulder season in Launceston — cheaper, quieter, and a genuine gamble. Highs average 15.4 °C, lows 6.4 °C, and rain falls on 12 days — nothing in the month is working against you.

May ranks 8 of 12 in Launceston: 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, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 15.4 °C days and 6.4 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest May day reached 23.8 °C and the coldest night fell to -0.2 °C, and the wettest single day dropped 50 mm — roughly 68% of the month's rain in one day.

May is moderately variable: 28 mm in the driest year against 200 mm in the wettest, around an average of 74 mm. Roughly two Mays in three land near that average, and the third does something else entirely.

Wind is light at 8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 87%, high enough to notice on the warm days without dominating them.

How May sits in the year

The month is on the way down: 3.6 °C cooler than April, with June dropping another 2.5 °C. The first week and the last are not the same trip.

Daylight in May

9.8 hours of daylight, losing 1 hours across the month. That is between Launceston's extremes of 15.1 and 9.2 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 15.7 °C in May — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. The sea peaks at 18.3 °C in February and bottoms out at 12.5 °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 Launceston versus nearby

If Launceston is one option among several, the nearby comparison is worth making. Devonport is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Burnie is the weaker option in May — within a degree on temperature, 4 days more rain.

So: May is a compromise. January is 25 points better and is what Launceston is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
