Weather in Devonport in March

Prime time. March is about as good as Devonport gets. Highs average 19 °C, lows 14.6 °C, and rain falls on 8 days — nothing in the month is working against you.

March ranks 3 of 12 in Devonport. Only February scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 8 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average March reaches 30 °C; the day barely swings — 4.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest March day reached 24.4 °C and the coldest night fell to 9.4 °C, and the wettest single day dropped 65 mm — roughly 100% of the month's rain in one day.

March is moderately variable: 9 mm in the driest year against 188 mm in the wettest, around an average of 65 mm. Roughly two Marchs in three land near that average, and the third does something else entirely.

Wind is light at 13.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 76%, high enough to notice on the warm days without dominating them.

How March sits in the year

Temperatures hold steady either side: 19.9 °C in February, 19 here, 17 in April. Nothing about the timing within the month matters much.

Daylight in March

12.4 hours of daylight, losing 1.4 hours across the month. That is between Devonport'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 18.1 °C in March — swimmable, but it takes a moment to commit. This is the warmest the water gets all year.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

March in Devonport versus nearby

If Devonport is one option among several, the nearby comparison is worth making. Burnie is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Launceston is close enough to be a coin toss — 4.2 °C warmer, the same number of rain days.

So: March works, with February the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
