The harder it blows and the more it rains, the better it will be for the 2015 champion.
The 25-year-old Otago rider is the only previous winner in the field and will start the 61st edition of the race as one of the favourites.
Evans is a decent climber but the Powernet lead rider knows he will need some help from Southland's weather on the flat sections to make up some time against the stronger climbers.
The Tour gets under way in Invercargill tomorrow and Evans is hoping the sun disappears.
``The long term forecast is looking really sunny and warm at the moment so I'm not too happy with that actually,'' he said.
``I'd prefer it to miserable. It suits my characteristics a lot better. The windier the better.
``I've got a couple of really big guys on the team for those windy stages.''
Evans said he was ``a little under the radar'' in 2015.
Not too many riders were looking out for him early on. He had been racing overseas and had to make an epic journey from China to Invercargill in two days just to make the startline.
The taxing trip was all worth it. He set up the victory with a storming ride on the Bluff Hill stage.
``I was a marked man from that point on but I guess a lot of people didn't think I would last the whole week.''
Evans proved more tenacious than some had thought. He anchored himself to the wheel of Australian Robbie Hucker all the way to the top of crucial Coronet Peak stage.
He then extended his lead with a strong individual time trial on the last day before cruising into Invercargill in the afternoon with the race wrapped up.
He became just the third Otago-based rider to win the tour after inaugural winner Kelvin Hastie in 1956 and Gordon McCauley in 1996.
Evans, who married Holly Todd earlier this month at Glenfalloch, missed the race last year due to a scheduling clash but brings some wonderful form into the Tour.
He was a force in the National Road Series in Australia this year. He won the Tour of the Great South Coast and took second in the Grote Prijs Beeckman-De Caluwe in Belgium.
Some of Evans' stronger competition will come from Michael Vink. He won the Bluff Hill stage last year and eventually finished runner-up to Aaron Gate.
He is a former New Zealand time trial and road champion and won the New Zealand Cycle Classic in 2014.
New Plymouth's Michael Torckler is one of the stronger climbers in the field and briefly wore the yellow jersey in last year's tour following an impressive ride up Coronet Peak.
Evans is also weary of German rider Raphael Freienstein.
The race gets under way with a 4.2km prologue team time trial around Queens Park.
As always, the Coronet Peak (day four) and Bluff Hill (day five) stages will be critical. Whoever has the yellow jersey following the Bluff Hill stage will be difficult to catch.
