Best Time to Dive
Planning your dive around the local climate is crucial for a rewarding experience at Richardson Beach Park. While conditions are generally favorable for diving throughout much of the year, specific periods present more challenges. From November through March, the area experiences stronger northwest swells, which can make entry, exit, and surface swims considerably more dangerous. Air temperatures are mildest from December to February, ranging from 13.5-15.2°C (56-59°F), and warmest from July to August, averaging 28.7-28.8°C (83-84°F). Wave heights average between 0.46 meters (July) and 0.91 meters (January), correlating with wind speeds varying from 21.5 km/h (13.4 mph) in July to around 31.1 km/h (19.3 mph) in January and October. Water temperature data is not consistently reported, but seasonal air temperature shifts can influence comfort levels above surface.
