Key Weather Factors in San Bernardino

Several factors influence the weather in San Bernardino. Understanding these can help you better prepare for your visit.

Lake Ypacaraí

The presence of Lake Ypacaraí significantly affects the local climate. The lake moderates temperatures, making the surrounding area slightly cooler in the summer and warmer in the winter compared to inland areas. The lake also contributes to higher humidity levels, especially during the summer months. Additionally, the lake can generate localized breezes, which can provide some relief from the heat. Be aware that conditions near the lake can change rapidly, so it’s always a good idea to check the local forecast.

Humidity

As mentioned earlier, humidity is a significant factor in San Bernardino, particularly during the summer. High humidity levels can make the temperature feel much hotter than it actually is. This can lead to discomfort and heat exhaustion if you’re not careful. To combat the humidity, drink plenty of water, wear breathable clothing, and avoid strenuous activities during the hottest part of the day. Air conditioning can also be a lifesaver, so consider staying in accommodations that offer this amenity.

Rainfall

Wind

Wind patterns in San Bernardino can vary depending on the season. During the summer, prevailing winds tend to be light and variable, which can contribute to the feeling of stagnation and heat. In the winter, stronger winds can sometimes occur, especially during cold fronts. These winds can make the temperature feel cooler, so be sure to dress accordingly. The lake can also influence local wind patterns, creating breezes that can affect conditions near the water.
