How warm is it in California during April?

The temperature reaches around 22℃ during the daytime in April, falling away to 11℃ at night. The UV index will be moderate at this time of year, so not something to worry about for the average person. However, if you're going to be outside for long periods it's worth wearing a broad spectrum SPF 30+ sunscreen and UV-blocking sunglasses. Remember that bright surfaces, such as water and sand increase UV exposure.

On average, there will be 3 rainy days during the month, amounting to 59.7mm in total. That's broadly comparable with the amount of rain we see in England during the summer months, and would be considered dry. There's a small chance that you'll catch a thunderstorm during your trip.
