Weather in Devonport in July

A hard month. July asks something of you. Go in knowing what. Highs sit at 12.2 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.

July ranks 11 of 12 — near the bottom of Devonport's year. February is the month that works, and the swing between the two is 44 points, which is a different holiday rather than a slightly better one.

Rain on 15 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 12.2 °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 — 3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest July day reached 15.2 °C and the coldest night fell to 5.6 °C, and the wettest single day dropped 47 mm — roughly 45% of the month's rain in one day.

July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 201 mm against 22 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 105 mm average is a reasonable planning figure, not a promise.

Wind is light at 15.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, which at 12.2 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.

How July sits in the year

Temperatures hold steady either side: 13.1 °C in June, 12.2 here, 12.1 in August. Nothing about the timing within the month matters much.

Daylight in July

July sits at the dark end of Devonport's year — 9.5 hours of daylight against 15.1 at midsummer, gaining 0.6 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 13.1 °C in July — too cold to swim without a wetsuit. 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.

July 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, 5 days more rain. Launceston is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: July is a compromise. February is 42 points better and is what Devonport is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
