Seasonal calendar
Jastarnia's high season is July and August - Baltic water reaches 18–19 °C and the beach and hotel are full. Shoulder season is quieter: May and September keep the Baltic warmer than you'd expect with half the crowds, and October–November is prime kite season. January, February and March belong to spa and indoor-pool guests.
Twelve months across eight dimensions - weather, water, wind, crowds, and who each month suits. A short note from the apartment service team for every row, so you know not just what the numbers say, but what it actually feels like on the ground.

|---|---|---|---|---|---|---|---|---|
| January | 1 °C | 4 °C | 30% | 35 mm | 14 kt · westerly | 1/5 | 2/5 | Relax + spa |
| The quietest moment of the year. The beach is empty, wind is strong - most guests come for the 20 m pool, sauna and long breakfasts in „Czwarte Piętro\”. | ||||||||
| February | 1 °C | 3 °C | 35% | 28 mm | 13 kt · westerly | 1/5 | 2/5 | Relax + spa |
| Short days, long pool sessions. A good reset before spring - Valentine's and winter half-term nudge occupancy up briefly. | ||||||||
| March | 4 °C | 4 °C | 45% | 30 mm | 12 kt · westerly | 1/5 | 3/5 | Relax + spa |
| The Baltic is still cold but daylight stretches. The beach is long and empty, ideal for walks with coffee from the hotel's „Czwarte Piętro\”. | ||||||||
| April | 9 °C | 6 °C | 50% | 30 mm | 11 kt · north-westerly | 2/5 | 3/5 | Active |
| Spring wakes the kitesurfers - NW winds, water at 6 °C only for the hardy. Spa and pool remain calm. | ||||||||
| May | 14 °C | 10 °C | 60% | 35 mm | 10 kt · northerly | 2/5 | 3/5 | Couples |
| Baltic at 10 °C, gentle winds, light crowds. The long May weekend peaks briefly; the rest of the month belongs to couples and the active. | ||||||||
| June | 18 °C | 14 °C | 65% | 55 mm | 9 kt · northerly | 3/5 | 2/5 | Couples |
| Water at 14 °C, the beach starts filling, but still well short of July's peak. Long Baltic sunsets over the open sea. | ||||||||

| Peak season. Water 18 °C, long days, beach busy, hotel at full occupancy. Book at least 4 weeks ahead. | ||||||||

| September | 17 °C | 17 °C | 55% | 65 mm | 12 kt · westerly | 3/5 | 4/5 | Couples |

| October | 11 °C | 13 °C | 40% | 60 mm | 13 kt · south-westerly | 2/5 | 5/5 | Active |
| Kite season proper - SW winds at 13 kt, water 13 °C. Streets empty, spa full. | ||||||||
