On The Up: Weather-forecasting Rotorua tortoise predicts long hot summer ahead

Her track record, Hoyle claimed, showed “she’s better than MetService”.

After 65 years of owning Herman, Hoyle said it was impossible not to notice her seasonal habits.

“Her reaction to waking up and going to sleep … it coincided with the sort of weather we were getting”.

Herman spends the colder months tucked into a bale of hay, hibernating early if winter was set to be cold and resurfacing early when warmer days were coming.

She usually woke up around September 6, Hoyle said, but this year she stirred earlier than expected on August 28.

That’s a sign of “long, hot summer”, Hoyle said.

Earth Sciences New Zealand’s seasonal outlook for October to December predicted near-average to above-average temperatures nationwide, with the Bay of Plenty and the rest of the northern North Island likely to be warmer than usual.

Herman’s forecasts only applied to the Bay of Plenty, where she resided.

Asking her to predict the weather for the entirety of New Zealand would be “expecting a bit much”, Hoyle said.

But Herman has a habit of surprising people.

When Hoyle originally imported Herman from the Welsh Mountain Zoo, he guessed she was about 30, but was unable to confirm this as a fire destroyed the zoo’s records.

Hoyle also assumed the tortoise was male.

Tortoises were “very hard to sex until they get quite mature”, he said.

By the time it was realised Herman was actually female, the name had “stuck”.

She was also known for having a slightly unconventional diet for a tortoise.

While mostly vegetarian, Herman enjoyed a snail or two.

Alongside her diet of strawberries and lettuce, Hoyle believed the snails helped her shell.

Despite tortoises being categorised as slow, Herman once proved she could move well enough when she wanted to.

In her youth, she escaped her pen and made it 3km down the road to the Lynmore shops – a journey that took just three days, much to Hoyle’s surprise.

These days, her adventures occur closer to home.

She spends her time roaming the Hoyles’ 0.2ha (half-acre) Rotorua property and greeting curious local children who come to visit.

And if her early wake-up is anything to go by, Herman will be doing plenty of her favourite activity this summer – basking in the sun.
