Bay residents better enjoy the sunshine while it lasts because rain is on the way - a severe weather watch has been issued for Wednesday.
The watch is for the possibility of heavy rain reaching warning levels in the Bay on Wednesday and was likely to continue into Thursday.
MetService also predicted the remains of tropical cyclone Cook, which is hitting New Caledonia, to pass close to the North Island late in the week.
Meteorologists would continue to monitor the development of the cyclone.
People in the Bay have been advised to stay in touch with the latest forecasts in case the watch was updated to a full warning.
The warning was also in place for Taranaki.
