The chilly weather gripping the country is expected to continue into the weekend with forecasters predicting cooler nights for the country.

Records kept by the Nadi weather office show the lowest temperature measured this week was 15 degrees Celsius at Rarawai mill in Ba.

Other major centres also recorded low temperatures in the past week with Suva experiencing 21 degrees, Lautoka 17.6 degrees and Nadi at 18 degrees.

According to the weather office the cold spell is being caused by strong south east wind flow bringing in cold air from the south.

"These conditions are expected to continue into the weekend, however, it should start getting warmer next week," a forecaster said. Temperatures in the Western Division are expected to drop to 15 and 16 degrees Celsius in the weekend with the Central Division expected to record lows of 18 and 19 degrees.
