December milling wheat on Paris-based Euronext, was down 0.7 percent by 1611 GMT at 172.00 euros a tonne.
Chicago wheat futures fell for a second straight session on Monday as increased US government forecasts for US and world wheat production encouraged investors to book profits after a rally last week.
Most active wheat on the Chicago Board of Trade (CBOT) was down nearly 3 percent to $4.32-3/4.
The US Department of Agriculture (USDA) on Friday raised its outlook for US wheat supplies above expectation and also increased forecasts for this year's wheat harvest in Russia, where some crops have faced chilly, wet spring weather.
Euronext prices were also pressured by a lack of demand for Western European wheat.
Egypt's state grains agency GASC shunned the sole offer for French wheat at its tender over the weekend when it bought 360,000 tonnes of Russian and Romanian wheat.
"Egypt's purchase showed the disconnection of French wheat with its competitors," a trader said.
Market operators will be keeping an eye on weather in Europe with forecasts pointing to hot temperatures in the coming days.
German cash milling wheat premiums in Hamburg were little changed, capped by expectations that US hard red winter wheat will be used to supply much of the large purchase of 805,000 tonnes of wheat by Saudi Arabia.
Standard wheat with 12 percent protein content for June delivery in Hamburg was offered for sale unchanged at 1 euro over the Paris December contract. Buyers were seeking 0.5 euros under Paris.
"The market was underpinned by the Saudi purchase but failed to get upward impulse as there is a belief the US will supply much of the purchase," one German trader said.
"I think the US could supply about six of the 13 shipments bought, with one to two coming from Germany, one or two from Poland and the rest likely from the Baltic States."
Origins offered were the European Union, North America, South America or Australia with the seller having the option of selecting the origin supplied, Saudi grains agency SAGO said.
