Cold weather and rough seas did not deter the approximately 68,000 migrants who arrived in Greece last month, the European Union’s border protection agency announced Monday.

That number was 38 times higher than the number of migrants who made it to Greece last January, Frontex said in a news release, at the start of what was a record year for displacement.

Frontex has said more than 1 million migrants arrived in the European Union last year, nearly five times the 2014 total. Monthly arrivals topped 100,000 in July and remained at six-figure levels through December as refugees fled conflict-torn nations in the Middle East and Africa.

The U.N. Refugee Agency (UNHCR) says another 35,000 migrants traveled to Greece and Italy by sea during the first three weeks of February, bringing this year’s total arrivals above 100,000.

Only 13,000 people arrived in Greece and Italy in the first two months of 2015, the UNHCR said.

Frontex tried to place a positive spin on the migrant numbers released Monday, saying they represented a roughly 40 percent monthly drop from the 108,000 who arrived in Greece last December. The agency said winter weather contributed to the month-over-month decline.

But those who did arrive still added to a growing list of migrants who are seeking better lives in Europe, as nations face growing pressure as to how to cope with the massive inflow of people.

The vast majority of them arrive in Greece, the International Office for Migration (IOM) has said, as they are often shuttled on packed, unsafe boats across the Aegean Sea from Turkey.

Most of the migrants who arrived in Greece are from Syria, Iraq and Afghanistan, Frontex said.

Others arrive in Italy, a destination for sea routes that depart from Tunisia, Libya and Egypt.

Most of the migrants who arrived in Italy last month were from Nigeria, Frontex said.

The African nation is home to Boko Haram, which last year’s Global Terrorism Index dubbed the world’s deadliest terror group, and Fulani militants who have become increasingly deadly.

However, the migrants who are choosing to make the journey are also encountering some risks.

On Friday, The IOM, UNHCR and United Nations Children’s Emergency Fund on Friday warned of the increasing number of migrants who have drowned on their journeys to Europe.
