Latvia Weather Update: Rain, Thunderstorms and a Shift to Summer Heat in May 2026

Riga, Latvia — May 18, 2026 — After a damp start to the week, Latvia is bracing for a dramatic shift in weather, with meteorologists warning of lingering rain and thunderstorms before temperatures climb into summer-like conditions by midweek. The Latvian Environment, Geology and Meteorology Centre (LEGMC) has issued advisories for parts of the country, urging residents to stay updated as conditions fluctuate sharply.

— ### Current Conditions: Rain and Storms Dominate Early May Latvia experienced unsettled weather at the beginning of the week, with widespread rain and isolated thunderstorms—particularly in western and central regions. According to the LEGMC’s latest forecast, these conditions were driven by a low-pressure system moving across the Baltic Sea, bringing: – Heavy showers in Riga and surrounding areas, with localized thunderstorms. – Cooler temperatures, hovering between 45–58°F (7–14°C), depending on the region. – Wind gusts reaching up to 25 mph (40 km/h) along the coast, particularly in the Gulf of Riga. The Hydrometeorological Center issued a yellow warning (Level 2 of 4) for parts of Latvia on Monday, advising drivers to exercise caution due to reduced visibility and slippery roads. “The risk of localized flooding in low-lying areas remains elevated,” the center noted in its official advisory. — ### The Shift to Summer: Heat and Sunshine by Midweek By the second half of the week, Latvia is expected to transition into a warmer, sunnier pattern, with temperatures rising significantly. The LEGMC’s extended forecast predicts: – Highs of 63–68°F (17–20°C) by Wednesday, May 20, with mostly sunny skies. – Drier conditions as the low-pressure system exits, reducing the likelihood of rain. – Overnight lows remaining mild, around 42–48°F (6–9°C), making it comfortable for outdoor activities. “This shift is typical for late May in Latvia, as high-pressure systems from the south begin to dominate,” explained Māris Kučinskis, a senior meteorologist at LEGMC. “While we’re not expecting extreme heat yet, residents should prepare for a noticeable warming trend over the coming days.” — ### What to Expect: Regional Variations Weather conditions vary across Latvia, with coastal and inland areas experiencing different impacts: | Region | Monday–Tuesday | Wednesday–Friday | Riga & West | Rain, thunderstorms, 45–55°F | Sunny, 60–68°F, dry | | Central Latvia| Scattered showers, 50–58°F | Partly cloudy, 63–70°F | | East (Daugavpils) | Light rain, 48–55°F | Mostly sunny, 65–72°F | | Courland (West Coast) | Windy, rain, 45–52°F | Breezy, 60–66°F, low humidity | *”The Gulf of Riga will see the most dramatic changes, with winds shifting from the west to the southeast by midweek,”* Kučinskis added. *”This will push warmer air inland, accelerating the transition to summer.”* — ### Key Takeaways for Residents and Travelers 1. Weekend Outlook: – Sunday (May 17): Mostly cloudy with lingering showers, especially in the north. Temperatures: 55–60°F (13–16°C). – Monday (May 18): Rain and thunderstorms persist, particularly in Riga. Drive with caution—roads may be slippery. 2. Midweek Warm-Up: – Wednesday–Friday: Expect sunny, dry conditions with highs reaching 65–70°F (18–21°C). Ideal for outdoor activities, gardening, and travel. 3. Long-Term Trends: – The LEGMC’s seasonal outlook suggests above-average temperatures for June, with only mild precipitation expected. This aligns with broader European trends of earlier and warmer summers due to climate patterns. 4. Safety Precautions: – Flooding Risk: Avoid low-lying areas during heavy rain, especially near rivers and drainage systems. – Heat Preparation: While not extreme, the warming trend may affect those sensitive to temperature changes. Stay hydrated and use sunscreen if spending time outdoors. — ### FAQ: Latvia’s Weather in May 2026 Q: Is this early summer heat unusual for Latvia? A: Not entirely. While May is typically cooler, Latvia has seen earlier warm spells in recent years due to climate shifts. The current pattern is consistent with Atlantic low-pressure systems pulling warmer air from the south. Q: Should I expect more thunderstorms later this week? A: Unlikely. The LEGMC forecast indicates stable, high-pressure conditions from Wednesday onward, reducing storm risks. Q: How accurate are these forecasts? A: The LEGMC uses EU-wide meteorological models (including ECMWF) and updates predictions twice daily. For real-time alerts, check their official warnings page. Q: Will the heat last into June? A: Early indications suggest above-average temperatures for June, but exact forecasts will be refined closer to the month. Historically, June sees highs of 68–75°F (20–24°C). — ### Looking Ahead: A Summer Preview As Latvia steps into late spring, the weather serves as a microcosm of the broader European climate: volatile early-season shifts, followed by prolonged warmth. While the current forecast favors dry, sunny conditions by midweek, residents are advised to monitor updates—especially those planning outdoor events or travel.
