Late spring brings steadily milder weather and longer daylight hours; coastal areas warm sooner than inland. Crowds start to build toward month-end, and many outdoor attractions open for the season. May is a convenient shoulder month for sightseeing with generally good conditions.

Average temperature across Estonia in May.
By May the coast begins to feel alive: apple blossoms and lilacs open in Tallinn and parks, and daytime temperatures commonly reach 10-15°C. Sea breezes keep beaches cool - Pirita and Stroomi have a fresh, windy quality - while Lahemaa’s trails green up quickly. Ferry day-trippers start returning; pack layers for cool mornings and wind protection for the headlands.
Pärnu, Saaremaa, Hiiumaa
By May the west coast starts to feel summery: Pärnu buzzes with cafés reopening and beachgoers tentatively arriving, while Saaremaa reveals its stone fences and manor grounds in green. Sea temperatures are still cool but day trips and cycling around Kuressaare or Kärdla are enjoyable in 12-18°C air. Ferry bookings increase on long weekends; pack layers for changeable coastal weather and a light rain jacket for showers.
Soomaa, Põlvamaa, Viljandi
May softens the landscape: wildflowers and green shoots carpet the forests, and daytime temperatures often climb into the mid-teens in Viljandi and Põlva. Hiking becomes far more pleasant, but bog boardwalks can still be damp and mosquitoes start to appear toward month end - a good insect repellent is essential. Cultural events revive in small towns and rural guesthouses reopen for the season.
Otepää, Haanja, Võru
By May the highlands are green and cool, with daytime temperatures usually in the low to mid-teens and nights still fresh. Wildflowers and meadows around Haanja bring color to ridge walks, and the region’s small lakes are peaceful for early-season paddling. Accommodation and mountain-bike rentals reopen in earnest; pack both a light jacket and breathable layers for active days.
Narva, Jõhvi, Lake Peipus shoreline
May brings warming days and a clear sense of spring: trees leaf out and the countryside near Tartu and Mustvee becomes pleasantly green with daytime highs in the mid-teens. The lake remains cool, producing morning vapour that can add atmosphere to sunrise walks. Roadside cafés and small museums reopen for visitors - insect repellent is handy near reed beds as mosquitoes start to appear.
