No sudden increase in the numbers of people seeking shelter has been recorded, Lita Brice of riga City Council's welfare department told LETA.
Free places remain available at all seven shelters across the Latvian capital and due to the low temperatures they are staying open round-the-clock, she said.
The shelters are also providing food and medical care when necessary.
In total 703 places are available currently, but if necessary that number can be increased to nearly one thousand.
Brice also reminded Rigans to keep an eye open for homeless people who may be roughing it in unsuitable places: garden sheds, derelict buildings or on the streets themselves and to spread the message that places are available.
Riga is also running several soup kitchens to provide hot meals to those in need.
