The air is fully saturated with 100% humidity, thanks to a matching dew point of 9.1°C — perfect conditions for early morning mist on the lake or fog over the treetops. Winds are gentle from the south-southeast at 7 km/h, and visibility is a clear 24 km. The barometric pressure sits steady at 102.3 kPa, so conditions should stay fairly stable into the afternoon.

The temperature will climb to a pleasant high of 23°C, ideal for just about any outdoor plan. The UV index sits at 6, or high, so don’t skip the sunscreen, even if a few clouds linger.
This is peak spring comfort — warm, bright, and fresh — with no serious weather risks in sight.
