"We are still seeing strong production coming from Europe, US and Argentina. While the hot weather in Europe has slowed down the region's production growth, it is still tracking ahead of last year. US milk production is up slightly and Argentina's is up 6.8 per cent," he said in a statement.
In New Zealand, the season has got off to a positive start, mainly thanks to good weather and early calving in the South Island.
Hurrell said that global demand "is simply not matching current increases in supply".
At recent Global Dairy Trade events, prices for all products that make up the milk price have fallen.
"Demand for whole milk powder, in particular, continues to grow in China, and it remains strong across South East Asia, but it simply isn't matching current levels of supply."
Hurrell said Fonterra's move to provide a forecast range, rather than a price, was part of the co-op's e intention to "provide the best possible signals".
"We operate in a hugely volatile global marketplace, so it is very difficult to pinpoint an exact forecast farmgate milk price this early in the season," he said.
Hurrell said weather conditions can change suddenly and this can have a significant impact on the global milk supply.
"As a result, we have chosen to give a range of $6.25-$6.50 per kgMS and be clear that the advance rate is based on $6.25 per kgMS and the final price could be outside this range as we are still early in the season and up against considerable volatility. We, therefore, recommend farmers budget with ongoing caution," he said.
