Coastal towns and villages were affected in Dumfries and Galloway and the Western Isles, prompting warnings to motorists and householders.
Fire and rescue crews had to pump water from properties in Isle of Whithorn, Kirkcudbright and Kingholm Quay earlier today.
The seafront in Stornoway on the Isle of Lewis and parts of Benbecula were also flooded.
In the north, police warned people against "sightseeing" near the shore at Wick.
A Police Scotland spokesman said: "High seas and rising water can be very unpredictable. The public have been asked to please consider not only their own safety but also that of the emergency services in what could end up as a potentially life threatening situation."
Motorists were tonight warned of surface water on routes in the Strathclyde region.
The Scottish Environment Protection Agency (Sepa) has meanwhile issued flood warnings for Tayside and Fife.
Environment Minister Paul Wheelhouse said: "Local agencies are working to support those affected by the flooding in the Western Isles and the public should continue to heed flood warnings, with coastal areas at high tide requiring particular care.
"The Scottish Government is in regular contact with the Met Office, Sepa, Police Scotland, operating companies and other key agencies and continues to actively monitor events to ensure a robust response to these incidents.
"The public should remain vigilant to the conditions, especially around coastal areas. Keeping up-to-date with the latest information is crucial to communities vulnerable to flooding.
"I'd also advise people to prepare in advance for any travel, to drive to the conditions, adhere to police advice and allow extra time for any journeys they are planning to make. Anyone making a journey should check relevant websites such as Traffic Scotland for up to date travel information."
