The long weekend in May is approaching and you are probably wondering what the weather will be like by the sea. That's completely natural. However, before you start refreshing every current weather forecast, it's worth checking the long-term weather forecast viewed historically. Such data best shows what you can usually expect during the May long weekend in Jastrzębia Góra.
Weather for the May long weekend 2026 by the sea – what do historical averages say?
Does the weather at the seaside during the May long weekend mean a heatwave? Not necessarily. Historically, Jastrzębia Góra at this time more often offers fresh, sea air and moderate conditions rather than summer heat. That's the charm of this region. On one hand, you have the Polish sea, a cliff, the coast, and plenty of space, and on the other — fresher weather, which is perfect for long walks, cycling, or relaxing outdoors.
Looking at long-term averages, May by the sea is cooler than inland but very pleasant for walks, relaxation, and the first longer rest by the Baltic. During the month, the maximum daytime temperature usually rises from about 12°C to 16°C, and the minimum from 5°C to 9°C. At the very beginning of the month, that is precisely when May 1st and often May 3rd occur, the thermometer shows an average of about 12°C during the day and 5°C at night. By the end of May, it gets clearly warmer.
For Jastrzębia Góra itself, the May average is about 14°C during the day, 8°C at night, and about 51 mm of precipitation for the month. Statistically, this means roughly 11 days with precipitation. In practice, it means that rain and showers may appear, but just as often these are simply occasional showers rather than all-day drizzle.
Long-term weather forecast versus actual Baltic weather
How does a classic weather forecast differ from what a long-term forecast shows? The latter does not tell you exactly whether it will rain at 3:00 PM on a specific day. Instead, it shows what kind of weather is typical for the given time frame. And that’s why it’s so helpful when planning a trip for the long weekend.
In May, cloudiness in Jastrzębia Góra gradually decreases. At the beginning of the month, the sky is cloudy or significantly overcast about 52% of the time, and by the end of May about 47%. At the same time, the chance of noticeable rainfall during the day rises only slightly — from about 18% at the beginning of May to 21% at the end of the month. Average rainfall over a moving 31-day period stays around 34 mm in May. This is good news because it means that even if there are passing rain showers, they usually do not dominate the entire stay.

Weather for the May long weekend by the sea and comfort of stay
Why do so many people choose the sea at the beginning of May? Because even when it’s not very warm, the coastal climate gives something often missing in the city: space, peace, and a breath of fresh air. In Jastrzębia Góra, this works especially well as the place combines forest, cliff, and the Baltic Sea. Rosevia Resort & SPA itself emphasizes its location right by the sea, private beach access, pools, and SPA area, so even grumpier weather doesn’t spoil the trip.
This is exactly where you can make good use of any kind of May weather. When it’s a sunnier day, you choose the beach and a walk along the coast. When there’s more cloudiness or light rain, you can relax in the pool, sauna, or SPA. Rosevia also describes private beach access through the Rozewie Cape cliff and offers options for families and couples, which is perfect for a short May holiday.
Long-term forecast – does it always come true?
A historical long-term weather forecast provides a great reference point, but right before the trip it’s always worth checking the latest forecast. Services such as IMGW or weather portals then show more precisely whether there will be heavier cloudiness, storms, heavier rainfall, or simply warmer conditions than usual on particular days.
During planning, historical averages are very helpful. They show that the May long weekend by the sea in Jastrzębia Góra usually means temperatures around 12–16 degrees Celsius, moderate passing showers, but also plenty of opportunities for walks and relaxation by the Baltic.
