Regulars describe May here as genuinely unpredictable within a single day, one visitor recalling rain, strong wind, hail, sunshine and a swing from 15C to 25C all inside a few hours. Our monthly row averages that volatility down to 16.4C reading as 14C over 5.6C nights feeling 2C, with 32.7mm of rain across 5.9 days and a trace of snow, 0.3cm, still possible early in the month. Their consistent call is that mid to late May is the nicest stretch of the year here, cool being just as likely as warm rather than a given either way. Pack rainproofs and a t-shirt both, and a jacket for evenings regardless of how the day went. The sea stays cold at 7.9C. The record: humidity 66 percent, 13.1 hours of sun, an 18.8 kph wind and AQI 61.

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.
