पैर्नू में अगस्त का मौसम

Regulars point at late August rather than August: the European school terms restart, people go back to work, and the city thins while the weather still holds - once September starts they call it less predictable. The other half of the advice is hourly, not weekly. The ship tours work the old town through the day and are gone by late afternoon, so an early morning or an evening there is a different place from a midday one. Our row gives 21.8C days over 13.1C nights with 99.5mm across 11.4 days, 11 hours of sun inside 15.5 of daylight, and a 19.9C sea. The record: humidity 78 percent, a 20 kph wind and AQI 44.

Estonia's forum is realistic about December: subzero temperatures are common but not constant, this is the darkest stretch of the year, and rain is honestly just as likely as snow - a lot of December here means slush rather than a clean white blanket. Wind varies a lot day to day, from calm to blustery, so there's no single pattern to plan around. Pärnu's own beach town character goes fully dormant this time of year, but the coastal chill and short daylight hours are consistent with what the wider Baltic region sees this month.

Forum posters describe June across Estonia as genuinely hit or miss, even around midsummer - a lucky visitor gets blue skies and T-shirt weather, an unlucky one gets sleet, with July generally the more reliably warm month. Posters are consistent that any June rain tends to come as passing showers rather than prolonged, driving rain. Posters specifically flag a real upside for Parnu: the sea here runs 5-7C warmer than in Tallinn through June-August, a meaningful difference for anyone hoping for a swim. Posters generally recommend Parnu as a good base for exploring western Estonia if the weather turns inclement and a car isn't available, given its concentration of things to do compared to more spread-out surrounding areas.
