May Weather at a Glance
May averages 61°F / 16°C highs and 46°F / 8°C lows with 45mm precipitation over 9 wet days. Humidity 68%. Sunshine 9h daily. Daylight at 17 hours by month-end — sunrise 04:50, sunset 21:55. Lilacs bloom in Mežaparks late May (the canonical spring sight). Sea-temp climbs to 9°C — Jūrmala possible for the brave swimmer, but cold-shock real. Stork sightings peak (Latvia has Europe's highest stork population — they nest visibly on Mežaparks chimneys).
May Travel Advice
Pre-book Riga Marathon (mid-May) hotels 6-8 weeks ahead — central rates spike 30%. Independence Day (May 4) public holiday means museums + shops close (some); restaurants stay open and the Freedom Monument fireworks at 22:00 are the year's biggest civic event. First proper Jūrmala beach walks possible but bring jacket — Baltic coast wind is sharp. Lilac season in Mežaparks runs late May.
May Pricing Trends
Climbing toward summer peak: Grand Palace $260-420/night, mid-range 4-star $120-200. Flights from major hubs $400-800. Marathon weekend adds $50-150 hotel premium. Independence Day weekend (May 4) firm pricing.
