The heaviest downpour arrives in the evening and persists through the night
Over Latvia on Wednesday, a morning of clarity gives way to a slow, inevitable reckoning with weather — a southwestern cyclone pressing against a retreating high-pressure calm. By evening, rain will have claimed most of the country, and by night, the heavier work of the storm will begin in earnest. It is the familiar rhythm of seasonal transition: one system yielding, another asserting itself, and ordinary life caught in between.
- A deceptively clear morning will lull Latvia before clouds begin their quiet advance through the afternoon.
- Rain spreads unevenly at first — inland regions feel it sooner, while Riga and the coast hold out longer under cooler, sea-tempered air.
- A southwestern cyclone is actively displacing a high-pressure system, turning scattered afternoon showers into a broad, intensifying evening downpour.
- By nightfall, the heaviest precipitation of the period arrives, with conditions likely to disrupt travel and outdoor plans through Thursday morning.
Wednesday opens with clear skies across Latvia, but the calm is borrowed time. Through the afternoon, rain begins to filter in across scattered regions, and by evening the wet weather has spread to most of the country. The night brings the heaviest precipitation of the period.
Temperatures remain mild, ranging between 10 and 15 degrees Celsius, with a light to moderate northeast wind. Riga holds off the rain longest, with showers arriving only toward evening and air temperatures near 14 degrees. Along the coast, the sea keeps things noticeably cooler — closer to 10 degrees — a reminder that Latvia's western edge answers to a different authority.
The story behind the weather is one of competing forces. A high-pressure system has been holding the region in relative stability, but it is retreating before an advancing cyclone from the southwest. As that cyclone draws near overnight, it will be the agent of the period's most intense rainfall — transforming what began as a partly cloudy Wednesday into a thoroughly soaked Thursday morning.
Wednesday morning breaks clear over Latvia, but the sky will begin its slow transformation as the day unfolds. By afternoon, rain will start to move in across scattered parts of the country. After lunch, the wet weather will intensify and spread—by evening, most of Latvia will be under precipitation. The heaviest downpour is expected to arrive in the evening hours and persist through the night into Thursday.
Temperatures will hover between 10 and 15 degrees Celsius throughout the day, with a northeast wind that stays light to moderate. Riga will hold out longest against the rain, with showers arriving closer to evening as the air warms to around 14 degrees. The coast tells a different story—there, the sea's influence keeps things cooler, with temperatures settling near 10 degrees.
The shift in weather is being driven by two competing systems. A high-pressure area currently dominates the region, but it is losing ground. A cyclone is moving in from the southwest, and it will be the force that transforms Wednesday's scattered showers into Thursday's heavier rain. By the time night falls, that cyclone will have moved close enough to bring the most intense precipitation of the period.
The Hearth Conversation Another angle on the story
Why does the rain arrive so gradually? Why not all at once?
The cyclone is still approaching from the southwest. It's not overhead yet. What we see Wednesday is the leading edge of the system—the outer bands of moisture reaching us first. The heaviest rain comes when the cyclone itself moves in, which is overnight.
So Riga gets a break longer than other places?
Yes. The city is positioned in a way that the rain reaches it later in the evening. Coastal areas are already cooler because of the sea, so they'll feel the weather shift sooner.
What should people actually do with this forecast?
Plan outdoor activities for the morning and early afternoon. If you need to travel, Wednesday afternoon is still manageable. But expect roads to be wet and visibility reduced by evening, especially overnight into Thursday.
Is this unusual for May?
Not particularly. Spring weather systems like this are common—high pressure giving way to cyclones bringing rain. It's the rhythm of the season.
