There are four distinct seasons in Tacoma.

July, according to data, can be practically rain-free. Autumn (September-November) is characterised by gradual cooling and an increase in the number of rainy days, preparing the city for the winter season.

One of the key features of the weather in Tacoma is the pronounced rainy season, which occurs in late autumn and winter. In contrast, the summer months, especially July, are distinguished by low rainfall, creating favourable conditions for outdoor activities. Travellers should consider this seasonality when planning a trip: for sunny weather, it is better to choose the summer months, while for those who do not mind the rain and prefer a quieter atmosphere, other seasons are also suitable.

When planning a trip to Tacoma, it is important to be prepared for changeable weather and frequent rainfall, which is characteristic of this region for most of the year. The key principle of your wardrobe is layering. This will allow you to easily adapt to temperature changes throughout the day. An integral part of your gear should be comfortable waterproof shoes, as there are many rainy days, especially between October and April.

In the cold season, from November to March, when average temperatures stay in the range of 5-8°C, be sure to pack warm clothes: sweaters, fleece jackets, as well as a waterproof and windproof jacket. A hat, gloves, and a scarf will also be very useful. Given that there can be up to 20 rainy days in these months, a reliable umbrella or raincoat will become your faithful companions. In spring (April-May) and autumn (September-October), the weather softens, but a light jacket and rain protection are still relevant.

Summer months, especially July and August, are the warmest and sunniest in Tacoma, with an average temperature of about 20°C and maximum values reaching 25-26°C. Precipitation during this period is minimal (in July there is practically none). At this time, you will need light clothing: T-shirts, shorts, summer dresses. Nevertheless, evenings can be cool, so bring a light cardigan or jacket. Sunscreen and a hat are necessary for sun protection on clear days. Although summer, and especially July, is considered the dry season, a light raincoat in case of sudden rain (except for the almost always dry July, it is possible in other summer months) may come in handy, as the weather in the region can be unpredictable.
