Temperatures reached 34C in parts of Masterton yesterday, while Saturday saw 30C-plus temperatures across most of Wairarapa.
However, be prepared for a "considerable" drop later in the week.
Traditional swimming spots were surprisingly quiet on Saturday, possibly because many took advantage of free admission to Genesis Recreation Centre's pools in Masterton.
Cyclists travelling to Greytown from Wellington on Saturday for the Pashley Bicycle Picnic experienced a big rise in temperature after stepping off the train at Woodside, with Wellington a mere 25C that day.
Riders Silvana Tizzoni, Laura Christie, Rob Appleton and Kelly Williams from Wellington said they loved the ride from Woodside station along the former rail line to Greytown, but were glad of the shade offered at Stella Bull Park.
