Weather in St Paul Island

Stay informed about the meteorological conditions when planning your visit to St Paul Island. Below you will find the latest weather data, useful charts, and forecasts for the coming days.

The climate in which St Paul Island is located can be characterized as subarctic maritime, distinguished by high humidity, winds, and constant coolness. The ocean plays a key role in shaping the local weather, smoothing out temperature fluctuations: there is no exhausting heat here in summer, but extreme frosts, typical of the mainland, also happen extremely rarely.

The seasons replace each other quite smoothly, while the temperature regime remains surprisingly stable throughout the year. Summer here is very short and cool, with average temperatures around +8...+10°C, which requires warm clothing even in July and August. Winter is relatively mild for northern latitudes, with thermometer readings often balancing around the zero mark or dipping slightly below freezing.

A characteristic feature of the local weather is the large number of cloudy days and frequent precipitation. Rain, drizzle, or snow can fall here in any month, and the number of "damp" days in the year is very high, especially in the autumn-winter period. When setting off for this unique corner of the United States, tourists should definitely take waterproof and windproof equipment with them.

The climatic conditions in which St Paul Island is situated are dictated by its location in the open sea. Cool and humid weather reigns here with a very small annual temperature amplitude. Winter on the island is quite mild by northern standards, but windy: January usually becomes the coldest month with an average reading of about -1.0°C. Even in February and March, the thermometer rarely drops below -2°C, which spares tourists from the extreme frosts characteristic of the continental part of the region.

The summer season here is completely unlike a traditional summer: there is never any scorching heat or stifling mugginess. The warmest month is August, when the air warms up on average to 9.8°C, and daily maximums barely cross the +10°C mark. June and July also remain quite cool with average temperatures from +6°C to +8.5°C. This time of year is suitable for travellers seeking freshness and wishing to rest from the scorching sun.

A remarkable feature of the temperature regime is the surprising stability throughout the day. The difference between day and night readings is minimal and often amounts to just 1–1.5 degrees. Transitional seasons are protracted: spring arrives very slowly (in May it is only about +2.6°C), while autumn retains the heat accumulated over the summer for a long time, remaining warmer than spring right up to November.

When planning a trip to St Paul Island, it is important to consider the specifics of the local climate: a small amount of precipitation falls here, but cloudy weather is a frequent occurrence. Instead of torrential downpours, light drizzle, constant fog, and high air humidity are characteristic of the island. The total volume of precipitation is small (only 1–4 mm per month), but an umbrella or raincoat will be useful in almost any season.

The wettest period in terms of frequency of bad weather falls on late autumn and early winter. From October to December, the number of days with precipitation reaches its peak — for example, in December there can be about 24 of them. In the winter months (January, February), when the average temperature drops below zero, rains give way to snowfalls, which is typical for this region.

The end of spring and the beginning of summer can be called a relatively dry season. June is the month with the lowest frequency of precipitation, when it rains on average only 9 days. However, even during this period, while in the United States, it is worth keeping waterproof clothing at hand, as the weather on the island is changeable and a clear sky can quickly be covered by clouds.

When preparing to visit St Paul Island, be ready for cool and damp weather at any time of the year. Even in the warmest months — July and August — the average temperature holds around +9...+10°C, so light summer clothes will hardly be useful here. The main principle of your wardrobe is layering. Start with quality thermal underwear, add a warm sweater or fleece jacket, and put a reliable jacket on top. This will allow you to regulate heat exchange depending on the changing conditions.

Pay special attention to protection from moisture and wind. Statistics show a large number of rainy or snowy days (from 9 in summer to 24 in winter), so a waterproof and windproof windbreaker or membrane jacket with a hood is a mandatory element of equipment. Footwear should be comfortable, warm, and waterproof, preferably with a non-slip sole for comfortable walks on wet ground.

Do not forget about warm accessories: a hat, scarf, and gloves will be relevant almost all year round, as cool winds are possible even in summer. In the winter period, when the temperature drops slightly below zero, it is worth taking woollen socks and an additional set of warm clothing. Sunglasses may also be useful, but rather to protect the eyes from the wind than from the bright sun, as the weather is often cloudy.
