SAN DIEGO — Tuesday afternoon high temperatures will be above seasonal norms.
- Coastal highs 66°-73°, normal around 68°.
- Inland highs 74°-81°, normal around 76°.
- Mountain highs 71°-79°, normal around 63°.
- Desert highs 92°-97°, normal around 86°.
Low rip current risk at the beaches with water temperatures around 60°. Wave heights are 2'-3'. A west swell decreases through the morning with a constant underlying south swell.
The UV Index for San Diego is 9, very high. The high levels of UV radiation from the sun may cause skin damage. It is strongly recommended to take precautions to reduce exposure.
Marine layer low clouds may be low enough to reduce visibility in some areas Tuesday morning. The patchy fog and low clouds should clear by 9 AM. The marine layer will keep coastal and inland areas fairly humid as dew point temperatures increase into the middle and upper 50s through the day. Mountain and desert dew points will top off in the middle 40s.
The Week Ahead:
High pressure strengthening over the region will send afternoon high temperatures well above average by Thursday. High temperatures will reach 5-18 degrees above average.
Low clouds and patchy fog are possible each morning. High pressure suppresses the marine layer to lower depths, causing clouds to lower to surface levels.
High pressure will weaken Friday through the weekend due to a low pressure coming in from the Pacific Ocean. Temperatures will reach about average levels for the coast and inland areas by Saturday.
Low pressure is forecast to push inland on Sunday night, resulting in the chance for light showers Sunday evening into Monday morning.
