Weather in Oak Harbor

Stay informed about the current weather conditions in the city of Oak Harbor. Below are the latest data and forecasts to help you better plan your time and prepare for your trip.

The climate in Oak Harbor can be described as temperate marine, characterized by mildness and a lack of extreme temperatures. Thanks to the influence of the ocean, there is no exhausting heat in summer or severe frost in winter. The weather generally encourages a comfortable holiday, though travellers should consider the distinct seasonality regarding precipitation.

Summer in the city is the most pleasant period: from June to September, warm and predominantly dry weather sets in. In July and August, the air warms up on average to 17–20°C, and the number of rainy days is minimized (only 4–6 days per month). This is the ideal time for walks and active outdoor recreation.

The winter period, conversely, is characterized by high humidity. From November to January, the temperature hovers around 5–7°C, but it rains very frequently — up to 21 days a month. If you are planning a trip at this time of year, be sure to take waterproof clothing and an umbrella, as overcast skies and frequent rainfall are typical companions of the local winter.

The temperature pattern in Oak Harbor is distinguished by its mildness and absence of extreme fluctuations, which is typical for coastal zones. The annual temperature range is quite narrow: average figures vary from a minimum of 5.0°C at the end of winter to a maximum of about 17.5°C at the end of summer. According to statistics, the coldest month is February, when night temperatures can drop to 3.0°C, and the warmest is August, delighting visitors with stable warmth.

Summer in this region can be called moderately warm and very comfortable for those who cannot tolerate sweltering heat. In July and August, daily maximums reach an average of 19-20°C, creating a pleasant atmosphere for walks, while nights remain refreshing (around 14°C). Here you will not encounter parching heat; the weather encourages long stays in the fresh air without the risk of overheating.

The winter period passes quite mildly, without severe frosts. In December and January, the average temperature holds at the level of 6°C, and night figures rarely go deep into the negative, remaining within 4°C. It is worth noting that the difference between day and night temperatures in Oak Harbor is small throughout the year — the amplitude of fluctuations often amounts to just 3-5 degrees, making the daily temperature progression smooth and predictable.

Precipitation in Oak Harbor has a clearly defined seasonal character, which is important to consider when planning a trip. The wettest period lasts from late autumn to mid-winter. The "wettest" month in terms of rain frequency is January, when precipitation can fall on average for 21 days. November is also distinguished by high humidity, showing some of the maximum annual rainfall values.

Summer, on the contrary, delights travellers with dry and more stable weather. July is considered the driest month: at this time, only about 4 rainy days are recorded, and precipitation volume falls to a minimum. August is also favourable for tourism, maintaining a low probability of rain and allowing you to enjoy outdoor walks without an umbrella.

In the transitional seasons — spring and early autumn — the weather is more changeable, with the number of inclement days ranging from 10 to 16 per month. Given the mild temperature regime, the main type of precipitation is rain. In winter, it can be frequent and prolonged, while in summer, rains are usually short-lived. Snowfalls happen here quite rarely, as average temperatures even in winter remain positive.

When packing for Oak Harbor, it is worth remembering the changeable marine climate of this region, so the main principle of your wardrobe should be layering. Since the weather here is rarely extremely hot or freezing but is often accompanied by precipitation, your most important companion will be a high-quality waterproof windbreaker or a raincoat with a hood. In the period from October to March, when rains occur particularly often and humidity is elevated, it is recommended to have a compact but sturdy umbrella resistant to wind gusts.

For a summer trip (July and August are the driest and warmest months), t-shirts and light trousers will be suitable; however, evenings by the water can be cool, so a fleece jacket or hoodie is mandatory. In winter and the off-season, when the temperature fluctuates from +5 to +10 °C, it is worth adding an insulating layer: woollen sweaters, a scarf, and a hat to feel comfortable in the wind. A heavy winter fur coat is unlikely to be needed, but a light down jacket will be just right.

Pay special attention to footwear: it should be maximally comfortable for walking and, preferably, water-resistant. Leather trainers or light trekking boots will be an excellent choice for walking around the city and parks in any weather. Also, despite the cloudiness, do not forget sunglasses and sunscreen in the summer months, as UV radiation near the water remains active.
